 In one case, for example, they go to Prajāpati, their father, to understand what is Self (Atman, soul) and how to realize it.The first answer that Prajāpati gives is simplistic, which the Asuras accept and leave with, but the Devas led by Indra do not accept and question because Indra finds that he hasn't grasped its full significance and the given answer has inconsistencies.Edelmann states that this symbolism embedded in the Upanishads is a reminder that one must struggle with presented ideas, learning is a process, and Deva nature emerges with effort.
