Life events and interactions with a variety of people can tend to disturb the balance of people who have not yet reached that perfect inner balance, but are striving to do so. (Effect of others on your chakrAs and breathing).
Chanting the Vishnu Sahasranamam is one of the many ways of regaining your balance.
One interesting thing is that sometimes the hands automatically adopt different mudrAs associated with different cAkrAs to reflect the state of the mind as pArAyaNam progresses.
When you feel the greatness of viSNu who you are praising, both your palms face upwards.
When you feel one with viSNu, then your palms reflect the abhaya mudra!
