The mind which is tied to the ego-sense and notions of pleasure and pain, is the seed for this samsara or world-illusion.

The mind of a jivanmukta is not swayed in the least from its utter equanimity by any kind of pleasure or pain, anymore than a mountain is blown away by someone blowing it with his breath. Such a mind is totally unaffected in great honor and festivity and in great calamity.
