Samadhi is the eighth anga of Patanjali’s ashta anga yoga.
At present, you may follow this link.
You may also read my article, meditation as a way to divinity – the link is available on the site-map on the right hand banner.
It is possible that I may write about samAdhi later.
Many saints attempt and attain that state, through yOga and tantra.
It appears that the way of vEdAs, upaniSads and Bhagavad Gita, while still being in samsAra, is the way that this mind-body-self has set off on.
With salutations to Patanjali, I sign off on this mini-series on ashtaanga yoga.
