Prajapati's three kinds of children finish their studentship and in turn ask him to tell them something. To each he says only the syllable da and asks whether they understood. The gods hear the command to restrain themselves, the men to give, the Asuras to be merciful, and each is told that is right. The heavenly voice of thunder repeats the syllable three times, and the text says restraint, giving and mercy should be taught.
