68-11 “Your questions are very nice. Yes, the Supersoul and the soul are both unchanged. The difference is that in material contact, the soul appears to be changed. But the Supersoul is not affected by material contamination, therefore there is no sign of change. The change of soul is like that water becomes ice in contact with the refrigerator. And as soon as there is temperature the ice again becomes water. Similarly, the changing nature of the soul is just like the change of water to ice. The tendency of ice is to melt and become water again. So due to contamination of matter, the soul by illusion identifies with material existence. But the tendency is to melt again to Krsna consciousness. So when there is sufficient temperature in contact with bonafide spiritual master, his life is successful. And to be fortunate, there must be sincerity, and Krsna will lead him to a bona fide spiritual master.
Purusa means God or Krsna. Atma, there is Paramatma and jivatma. Both are atma because they are spiritual, but the living entities are called jivatma. Jivatma means the small particle of atma which has the tendency to fall down in the material atmosphere. He is called jivatma. And Atma or Supersoul, Who never falls in material contamination is called Paramatma or Supersoul. And because He does not fall under material illusion, His name is Acyuta—Acyuta means never fallen.”

68-12 “The answer to your question about the marginal energy is that the jiva soul is always called marginal energy whether he is in the spiritual world or in the material world. There are instances where marginal energy jiva souls have fallen from the spiritual world, just like Jaya and Vijaya. So the potency to fall under the influence of the lower energy is always there. And thus the individual jiva soul is called as Krsna’s marginal energy.”
