The Mahabharata/Book 1: Adi Parva…
“ It is thus, O Ashtaka, that the gross and visible body developeth from the subtile essence.'"Ashtaka asked, 'After death, the body is burnt, or otherwise destroyed. Reduced to nothing upon such dissolution, by what principle is one revived?' Yayati said, 'O lion among kings, the person that dies assumes a subtil form; and retaining consciousness of all his acts as in a dream, he enters some other form with a speed quicker than that of air itself. The virtuous attain to a superior, and the vicious to an inferior form of existence. The vicious become worms and insects. ”
