The foolish cannot understand how a living entity can quit his body, nor can they understand what sort of body he enjoys under the spell of the modes of nature. But one whose eyes are trained in knowledge can see all this. The endeavoring transcendentalists who are situated in self-realization can see all this clearly. But those whose minds are not developed and who are not situated in self-realization cannot see what is taking place, though they may try.

Srila Prabhupada’s translation of Bg 15.10, 11
