 Prajapati tells the Devas to observe the virtue of temperance (self-restraint, "Dama"), the Men to observe the virtue of charity ("Dana"), and Asuras to observe the virtue of compassion ("Daya").At the end of the chapter, the Upanishad declares that these are three cardinal virtues that should always be observed by all Devas, Men and Asuras.Medieval era Indian scholars, in their "Bhasya" (review and commentaries) on the Upanishads, stated that the discussion of Devas and Asuras in the Upanishads is symbolic, and it represents the good and evil that resides and struggles within each human being.
