Everyone knows that, Hanuman, the son of the wind, vayu deva, is the fastest. Right? Well, the Isa Upanishad, tells us of one so fast that even the Devas could not catch up with That. (na enat devAh aapnuvan pUrvam arSat : Isa Vasya Upanishad). The Kena Upanishad tells us that Uma Haimavati, appeared in the very same place and explained the nature of ”That” Brahman to Indra. Some think of Her as Brahmavidya. The Devi Bhagavatam tells us that She herself is the Brahman.
We have thus far identified Lakshmi Devi, who is an aspect of Devi, with Light. (All the links to the previous posts on this topic are at the bottom of this page. Please read them before debating.)
And we have learnt from physics, that Light is the fastest of all. We can’t catch up with light.
Light is made up of massless particles called photons. The moment a photon is created, it quickly accelerates to c = 3*10^8 m/s
Nothing can go faster than a massless particle in vaccuum!!
And thus Lakshmi Devi, Light, who “is never still in one place”, is the fastest one in the Universe., and also the ‘lightest’! Only “he who is everywhere”, Vishnu, can be her darling, Lakshmikantha.
Of course, by “tat”, the Isa Upanishad refers to the Atman, the Brahman, which is Sarva Chaitanya or Devi as per Sankaracharya (Tat Tvam Asi) and as per Devi Bhagavatham.
And we have previously considered that the bio-chemical-electrical activity of the brain which we understand as consciousness or Chaitanya is also an aspect of the Devi. But these nerve signals are not as fast as sound or light. The fastest recorded wind speed is 113 m/s and the fastest nerve signal is 120 m/s, so Chaitanya is certainly faster than Vayu Deva, though not by very much.
Common Sense is a poor guide in the domains of the very fast and the very small.
For many thousands of years, humans have studied the rules that govern objects and activities on our scale.
Then we discovered that all the rules we framed are not highly accurate or highly truthful but they serve asExcellent Approximations in our scale of things, in our frame of reference. Things change drastically on other scales, where these approximations and methods are invalid.
- For an ordinary human being, light is extremely fast, for an astronomer, light just ambles along taking years to reach from the stars to the earth.
- For a particle physicist, c, the speed of light, is a convenient unit of speed.
- While astronomers like to use parsecs (3.26 light years) as a unit of distance and we would like to use km, particle physicists use 10^-15m (a femtometer or fermi) as a unit of distance. 1 fermi is about the size of a proton.
- The time it takes a particle to cross the nucleus is 10^-23s. The typical lifetime of a long lived particle is 10^-10s.
- 1 C, a coulomb of charge can light a lamp for 1 s. A proton and an electron have 1.6*10^-19 C of charge.
- The unit for mass is kg and energy is Joule at our scale.
- Because of the mass-energy equivalence, we use the same units for mass and energy when talking about particles, the electron volt. 1 eV = 1.6*10^-19 J. So when we say that the mass of a proton is 1 GeV or the mass of an electron is half a MeV., we know that we are talking about the equivalent mass of that much energy.
- The spin force or spin of an electron is about 10^-34kgm^2/s.
We need not only different units of measurement, but different methods of measurement at such tiny scales. And there are limitations on such methods, which lead us to all sorts of new rules., which we shall look at over time.

All of us are clear that the past really happened because we remember it. But you only have to ask two people about a given event to get very different accounts.
- they don’t want to “admit the truth”
- they actually experience the event differently from different vantage points
- they use different words to represent the same experience of a given event.
What has happened is at least as much in your head as it is out there in the past.
No one is clear about “what happens next” and a lot of us are anxious about it. Am I going to get what I desire, lose what I like – eg my life, my mind, my love, my health, my wealth, my reputation? As a result a lot of brain activity is centered around what is going to happen and what we can do to influence what happens. Since most human problems are similar many human dreams and nightmares are similar.
My Veda Guru, is pretty relaxed about most things because she is pretty certain that everything is predecided at birth and we just play out our roles, learning what God plans to teach us in this life and then passing his tests.
Everyone else that I know personally, including myself, is egoistic – they accept doer-ship and spend a lot of time wondering what they should do.
They seek the advice of elders and well wishers on what course of action they should take, they consult astrologers on whether it is a good time to do what they are planning to do, they seek the help of God to succeed in their endeavours and then they embark on their ventures.
A few people also pay attention to their dreams.
There are the frightening nightmares that accompany low blood sugar and anxiety and the rosy dreams of wish fulfilment. We dismiss most of these as just a dream.
Then there are the brilliant idea dreams of music and electronics designs and solutions to all of humanity’s problems, which are so silly on waking up.
Amidst all this incessant brain activity, we get a few dreams that actually “happen later” or are “meaningful even on waking”. Sometimes these also occur like “visions” or “ideas” in meditation. Sometimes they occur like Deja Vu. Sometimes you just know what people are going to do or say next. You have a flash about what they are thinking. You know about their past just taking a look at them. You “know”!
Knowing, understanding, recognising is about Cognition. Doing this before something happens is pre-cognition.
While most humans have rather bad memories, almost everyone has no pre-cognition at all. I wonder whether the spiritual practice that helps you see the future, kind of helps you forget the past. And whether the ability to see “into” people, goes with losing your ability to handle them or deal with them at the usual layer.
On the whole my dreams have guided and helped me. They have given me hints of diagnoses before the doctors figured it out, they have told me what would happen next if I went down one of two alternate paths, and showed me how things would get better when they looked like they were going bad. They also showed me what my life would be like, and what I could not change. I rely on my dreams to help me make major decisions.
I have read books on dream interpretations and sought the help of people who said they understood dreams. And I have used them to understand myself and improve myself and my life.
Clearly I believe that future ‘certainly’ and the past ‘probably’ can be changed. I think it’s like you can choose which path-of-time you can go down, just as much as you can choose which turning you will take on a road. And clearly I believe that you can discuss with divinity (through prayer) what you desire and fear and them make a dRDha sankalpa (firm will) that this is the path you will take.
A few dreams I want to share, you might have use for them :
- In a recent dream Sri Shirdi Sai Baba appeared and gave me a message. While I revere him when I visit his temples, I am not an ardent devotee the way for example Radhika, my student is. He was telling me that all action and decision is only from paramAtma. When I wasn’t getting it, he showed me a sanskrit text that said, “viSNuh eva Is’varah”, Vishnu alone is Is’vara (the Lord), and the dream ended. I thought it was important that I write this dream down. I have never read any of this Baba’s books and know about him only in an ambient sort of way.
- Another one is a rather old one. It showed me enter a place, take a left turn, six times to enter terrible hellish experiences which dissolved only when I chanted the name of SriRama श्री रामand the seventh time, I turned right and there was Rama seated on a small dias with lamps around him and a few people sitting peacefully around me. I found a place to sit at the back of the well-lit room and there I was happy for eternity. The dream ended there!
Agni is so important to us that when Veda Vyasa वेद व्यास organised the Veda Mantras into Rg, Yajur, Sama andAtharva, he put the Mantras of Agni first! (While chronologically mantras of the Atharva Veda are first, when Vyasa classified the mantras, he put the mantras useful for japa, ie, the Rk mantras into the Rg Veda, the first among the Vedas, not for chronology but for importance in spiritual sadhana. (Practice).)
What is Agni?
In most modern Indian languages, the word Agni or its variants mean fire.
What is fire?
Fire is a chemical reaction. Chemical reactions take place by electrons belonging to atoms re-arranging themselves. If an electron moves from a sodium atom to a chlorine atom, then the sodium atom becomes a positively charged ion and the chlorine tom becomes a negatively charged ion. Then these ions are held together by electrical forces and give us the sodium chloride we love as salt. There are many, many kinds of chemical reactions and ways in which atoms bond to make new compounds.
What we call fire, is a chemical reaction that involves oxygen. As an example take a piece of wood that has carbon and hydrogen in it. Add energy to it in the form of heat. At some point the hydrocarbons break up. Then oxygen reacts with carbon to form carbon dioxide and with hydrogen to form water vapour. But where does the “fire” – the heat and light come from? The heated up carbon (and other) atoms rising in the air start throwing off (radiating) electromagnetic energy. Lower frequencies of EM energy are heat and higher frequencies EM energy are light. Neils Bohr said that when electrons in atoms, change their energy states, electromagnetic energy is emitted or absorbed.
What is jaTara Agni?
Jataraagni is our digestive “fire”, the chemical reactions that digest our food. Krishna tells us in the Bhagavad Gita, that He becomes the vais’vAnara (universal person), enters the bodies of living things and digests the food. This does not look like a bonfire!
There is also, a legend of Agni hiding in the ocean waters, which we shall come back to at a later point in time.
Agni is associated with the movement of electrons.
As a chemical reaction in fire and digestion, as stream of moving electrons in electricity.
When electrons “jump” the “right” energy states photons can be emitted.
Sri Suktham : telling Agni to bring Sri!
In Sri Suktham, we tell Agni, the one born of Vedas (jAtavEda) to bring Lakshmi! (lakshmIm jAtavedO ma Avaha)
We have previously understood Lakshmi as light. (See links at the bottom of this page).
Now, we tell fire to go bring us light.
We tell the electrons to release photons!!
Of course, when we chant this mantram, as a Rg Vedic Mantram for japa, the light we seek is the light of illumination, when we chant this as a yajur mantram along with the araNi sticks and different Vedic Swaras we also want a physical fire to start up.
Today we light a match without any invocation and a fire starts up, or we press a switch and an electron current flows. So we don’t treat these events as sacred. We don’t see the need to entreat a match to light up, out techniques are more perfected.
But my great grandmother did and my Veda Guru does treat the switching on of a lamp or the lighting of a cooking fire as very sacred things. And there is an additional illumination that was/is reflected in their faces and eyes., because they view(ed) energy as divine, sacred and something worthy of respect!
Light of course is what it is. The trouble is with humans. In the case of light – it is Physicists.
To illustrate : Let us take Vasantji for example. He has called me a guru, rishi, a spiritual scholar and so on. One of my work friends called me a “kasaiee” meaning butcher, about 20 years ago when I was actually quite a nice person in my own eyes. And recently some one wrote in their blog that, though my work was something of an oversimplification, it was at least unbiased and without an agenda. All these nice people are performing an action called stereotyping. They are trying to put me in a box, so that they can deal with me, manage me and predict me. Of course one of my managers said that I was unmanageable and unpredictable, by which he was saying that I did not belong in any box that he had previously found useful. Finally everyone told me from my childhood upwards that I was “different”.

Physicists like to understand light. They like to model it with mathematical equations. They like to predict how it will be have in different situations. Engineers like to use this information and bend light to their will. For eg in a fiber optic cable.
When physicists first started to understand light, they did some experiments and tried to observe what it did.
They listed all its properties.
Some properties qualified Light for the Wave Stereotype box.
Some properties qualified it for the Particle Stereotype box.
Finally they said that light is produced and absorbed as if it were a particle (ie that particle mathematical model works) and it travels as if it were a wave. (ie that wave mathematical model works).
Then they tried to write longer equations taking more things into account to see if they could use one mathematical model which would describe the behaviour of light under all conditions.
That would be like saying that Satya is a nice enough person when she writes but if you meet her in person she is likely to bite your head off! Humans sit around in groups and gossip about other people, model and stereotype them. If housewives do this this called gossip. If corporate men do it it is called networking and ‘grapevine’ing. When Physicists do it about light it is called a conference.
What I am trying to say is that Light is Light and has been so before there were humans around to observe it and model it. We are the ones who initially evolved two different kinds of models and were astonished when Light does not fit the one or the other under all situations!
I have said that Light is an aspect of Sakthi Devi and that she is called Lakshmi, in the Vedas – Sri Suktham.
However many people worship Lakshmi Devi to get money (Dhana). No less a persona than Indra called Lakshmi as Mahamaya (the great illusion), Mahasakti (the great power/energy) and Jagan Mata (the mother of the world). People also worship for Siddhi, Buddhi, Bhukthi, Mukthi, Vijaya, Dhana, Dhanya for courage, illumination, metal stability, peace of mind and so on.
I am a firm believer that even thinking of Devi will make problems of every kind vanish and bring every form of prosperity.
This puzzles people too. They are surprised that someone who understands and trusts science can believe that praying to Devi will help. They see it as manas-s’anti.. not as reality. I am certain that Physicists have a far better understanding of light than I do and I look to their continued research for continued guidance. And I try my best to understand them.
My own personal, subjective experience shows me that prayer works wonders. I respect the different Rishis and try to understand what they understood and taught. I think they had a far better idea on these matters than myself.
I understand Devi can be Lalita, Saraswathi, Lakshmi, Durga, Parvati, Tripura Sundari, Kunda, Satya, Radha, Sarada, Ganga, Godavari, Narmada.. as well as Kaalika, Nidra, Krodhaa… and Chandi. And that in all of her aspects, she looks after us. I may have a particular love for Saraswathi and you for Durga, depending on our own natures.
I understand that though Lalita and Kaalika are so different, they are descriptions of the same Devi. Much has to do with the observer and the circumstances of the observation.

The problem is that things interact without touching! How do two magnets “feel” each other’s presence and attract or repel accordingly? How does the sun attract the earth? We know the answers to these questions are “magnetism” and “gravity,” but what are these forces? At a fundamental level, a force isn’t just something that happens to particles. It is a thing which is passed between two particles. : http://particleadventure.org /interact.html
Suppose you try shaking someone’s hand. You feel it. Right? As opposed to waving at them from a distance?
But reality depends on the layer you are looking at.
On our scale, if we touch hot things we can burn and we can scrape or skin on rough surfaces.
But if we go way past the cellular level to the atomic level, then there appearsto be no such thing as touching at all! In the universe as we experience it, we can directly affect only objects we can touch; thus, the world seems local.
” The effect of one object on another is due to an electromagnetic force producing an action at a distance. As the two objects involved get closer together even down to molecular levels the force gets bigger.”
The entire universe is in a sense ‘untouched’ and ‘untouchable’.
If I try to shake your hand, the atoms in my hand repel the atoms in yours and won’t let them “pass through”. This electromagnetic repulsion is what we experience as touching.
Pushing, Colliding and all related effects are actually electromagnetic repulsive forces at work.
“At a fundamental level, a force isn’t just something that happens to particles. It is a thing which is passed between two particles. Particle physicists have found that we can explain the force of one particle acting on another to INCREDIBLE precision by the exchange of these force carrier particles. One important thing to know about force carriers is that a particular force carrier particle can only be absorbed or produced by a matter particle which is affected by that particular force. For instance, electrons and protons have electric charge, so they can produce and absorb the electromagnetic force carrier, the photon. Neutrinos, on the other hand, have no electric charge, so they cannot absorb or produce photons. The carrier particle of the electromagnetic force is the photon (). Photons of different energies span the electromagnetic spectrum of x rays, visible light, radio waves, and so forth.
Life is just a neat example of electromagnetic force! ” (http://particleadventure.org).
And thus we are back with Lakshmi Devi. Holding the Universe together.
Atoms usually have the same numbers of protons and electrons. They are electrically neutral, therefore, because the positive protons cancel out the negative electrons. Since they are neutral, what causes them to stick together to form stable molecules? The answer is a bit strange: we’ve discovered that the charged parts of one atom can interact with the charged parts of another atom. This allows different atoms to bind together, an effect called the residual electromagnetic force. So the electromagnetic force is what allows atoms to bond and form molecules, allowing the world to stay together and create the matter you interact with all of the time. Amazing, isn’t it? All the structures of the world exist simply because protons and electrons have opposite charges! : http://particleadventure.org/residual_m.html

When we want to look at something we usually “throw a little light on it”… ie we hit it with photons.
When you hit a TV or a book with photons, it absorbs a few and reflects a few and that gives you a clue about the TV or the book. Then you can go and pick up the book for example.
Electrons are tiny little critters. You hit an electron with a photon and it might absorb the photon. Its energy state will change. Its like hitting a candle with a ball.. something like that. Comparable energies and sizes and so on.
So its not magic. Just size.
Ever run a project where you had to generate so many reports that the very act of monitoring made you risk your deadline?
If you want to observe an electron and “leave it standing” you have to think of something other way!
How big is an electron?
According to one estimate, the size of an electron is : 2.82 x 10-13 cm and It’s mass is about 9.10938215(45)×10−31 kg See : http://www.dimensionsguide.com/what-is-the-size-of-an-electron/
But how big is a photon?
“…….of the physical dimensions of a photon. On that topic, I must say that since the photon consists of changing energy fields, the photon encompasses that volume of space in which those energy fields have significant effect.
Thus, if a photon from a radio wave passes close enough to a receiving antenna, it will transfer its energy to the antenna, giving rise to an electrical signal even as the photon itself ceases to exist. The “size” of the photon is that volume of space within which this phenomenon can occur.
The higher the frequency of the photon, the higher its energy level. Therefore, such photons will have a correspondingly larger field of influence than their lower-energy counterparts…..” (Source :http://www.play-hookey.com/optics/photon_characteristics.html)
“In the wave idea of light, colour is determined by the rate at which the wave wiggles; a rapid, energetic wiggle for blue and a more leisurely wiggle for red. You can measure the distance that the light travels for each wiggle, and this is the ‘wavelength’ – it appears to be less than a thousandth of a millimetre for light….
The apparent length (in the direction of movement) of a moving object gets smaller as its speed approaches the speed of light… Since a photon travels always at the speed of light then it will always appear to have no length at all. This is, of course, whilst it is on the move…
We cannot know its size or shape. The appearance of light itself turns out to be a real secret; we cannot see that which we use to see everything else” (Source : http://www.oxygraphics.co.uk/photons.htm)

The good news is that it’s not just light that has a dual particle-wave nature. All particles also have a wave behaviour! So while it’s true that there is no point in “hitting particles with photons”, or “throwing light” on small particles to observe them, you can hit them with tinier particles.
How do you do this? You take a tiny “probing” particle. Accelerate it to such levels that it has high frequency and a really short wavelength. Now hit the target particle with it. Now observe! (Reference)
A particle accelerator at home is your TV or Computer Monitor. (CRT not LCD).

Introduction to Accelerators at CERN web-site.
“The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles.
Two beams of subatomic particles called ‘hadrons’ – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. For decades, the Standard Model of particle physics has served physicists well as a means of understanding the fundamental laws of Nature, but it does not tell the whole story.” Source
CERN has used this LHC to measure the weight of anti-matter. Nose around the CER web-site and see if you find anything of interest to you.
from : https://ancientindians.wordpress.com/2011/08/02/particles-the-standard-model-strong-and-weak-forces-what-holds-the-nucleus-together-particles-changing-into-other-particles-kamarupadhari-particles/
Each group consists of six particles, which are related in pairs, or ‘generations’. The lightest and most stable particles make up the first generation, whereas the heavier and less stable particles belong to the second and third generations. All stable matter in the Universe is made from particles that belong to the first generation; any heavier particles quickly decay to the next most stable level.
“The Standard Model answers many of the questions about the structure and stability of matter with its six types of quarks, six types of leptons, and four forces. But the Standard Model is not complete; there are still many unanswered questions.
Why do we observe matter and almost no antimatter if we believe there is a symmetry between the two in the universe? What is this “dark matter” that we can’t see that has visible gravitational effects in the cosmos? Why can’t the Standard Model predict a particle’s mass? Are quarks and leptons actually fundamental, or made up of even more fundamental particles?” Source
There are four kinds of interactions between particles : Gravity, Electromagnetic, Strong and Weak.
A force is the effect on a particle due to the presence of other particles. The interactions of a particle include all the forces that affect it, but also include decays and annihilations that the particle might go through. Sometimes the words are used interchangeably, though that is not very accurate. We have discussed electromagnetic carriers (photons) already a bit and the standard model does not handle gravity well, so let us look at strong and weak forces.
To understand strong forces, we have to understand quarks.
Quarks have a kind of charge called color charge that has nothing to do with color. This is in addition to their electromagnetic charge.
While protons and electrons have electric charges of magnitude “1″. Quarks have electric charges of magnitude 2/3 and -1/3.
Quarks always exist in composite particles with a net integer electric charge and a net zero colour charge. These composite particles are called Hadrons.
A proton is such a composite particle. It is made of 2 quarks of 2/3 electric charge and one quark of charge -1/3.
A neutron is made of 2 quarks of -1/3 electric charge and one quark of charge 2/3.
Since protons (uud) and neutrons (udd) have three quarks each they are called the “baryon” type of hadrons.
Gluons (a kind of bosons) are the Strong-Force carrier particles.
“Three of the fundamental forces result from the exchange of force carrier particles, which belong to a broader group called ‘bosons’. Matter particles transfer discrete amounts of energy by exchanging bosons with each other. Each fundamental force has its own corresponding boson particle – the strong force is carried by the ‘gluon’, the electromagnetic force is carried by the ‘photon’, and the ‘W and Z bosons’ are responsible for the weak force. Although not yet found, the ‘graviton’ should be the corresponding force-carrying particle of gravity.” (Source)
Quarks carry colour charge, anti-quarks carry anti colour charge and gluons carry colour as well as anti-colour charge. Colour Charge is conserved in interactions just as anti-colour charge. Colour charged particles cannot be found individually.
“The quarks in a given hadron madly exchange gluons. This is what “keeps the quark together”. If you separate colour charged particles they tend to snap back together or the bond will break! The strong force between the quarks in one proton and the quarks in another proton is strong enough to overwhelm the repulsive electromagnetic force. This is called the residual strong interaction, and it is what “glues” the nucleus together.” (Source)
Weak interactions are responsible for the decay of massive quarks and leptons into lighter quarks and leptons. (Third and second generation into first generation particles.)
An electron is an electrically negatively charged first generation stable least-massive lepton that is found abundantly in nature.
“When fundamental particles decay, it is very strange: we observe the particle vanishing and being replaced by two or more different particles. Although the total of mass and energy is conserved, some of the original particle’s mass is converted into kinetic energy, and the resulting particles always have less mass than the original particle that decayed.
The only matter around us that is stable is made up of the smallest quarks and leptons, which cannot decay any further.
When a quark or lepton changes type (a muon changing to an electron, for instance) it is said to change flavor. All flavor changes are due to the weak interaction.
The carrier particles of the weak interactions are the W+, W-, and the Z particles. The W’s are electrically charged and the Z is neutral.” (Source)
“The strength of the interaction depends strongly on both the mass of the force carrier and the distance of the interaction in both electromagnetic and weak interactions. The difference between their observed strengths is due to the huge difference in mass between the W and Z particles, which are very massive, and the photon, which has no mass as far as we know. So these forces are together called electroweak forces” (Source
With this little foray into photons and other particles., let us turn back to gravity, relativity and space-time again for some time.

c^2 = permeability of free space*permittivity of free space.
As per Maxwell’s electromagnetic equations.
If speed of light varied from one inertial frame of reference to another, then physics would be different in every plane, car, planet and so on.
Of course Michelson and Morley also proved this experimentally.
Once we get this in our heads, we are getting ready for the theories of relativity.
Lakhmi, anupagAminI, whose movement is incomparable, light, moves equally fast in your frame of reference and mine. She is not partial to you or me.
Atoms are held together by the electromagnetic force carriers ie photons. The universe is held together by threads of light, by Lakshmi Mata!

Imagine a train called Time that is ferrying you along a line/cycle/pretzel/. . .
Some passengers sit facing the engine.
Some passengers sit with their back to the direction of travel.
Those facing the ‘future’ or facing forward have an inkling of what the view is going to be like. Rishis?
Those facing backwards can see what is past but not what is yet to come! Most people.
Thus pre-cognition and memory are just two sides of the same thing.
You can have the one or the other at a time.
(I keep imagining a side ways sitting person with eyes everywhere and a brain equipped to process the information. That is why all anologies are limited.)
