Human life is not meant to be wasted, like that of the animals, in sense gratificatory activities. Animals always engage in sense gratification — eating, sleeping, fearing and mating — but that is not the engagement of the human being, although, because of the material body, there is need of sense gratification according to a regulative principle. So in effect Devahūti said to her husband, “So far we have these daughters, and we have enjoyed material life in the aerial mansion, traveling all over the universe. These boons have come by your grace, but they have all been for sense gratification. Now there must be something for my spiritual advancement.”
