Then, a body of men made it their business to carry on these sacrifices. These were the priests, who speculated on the sacrifices, and the sacrifices became everything to them. The gods came to enjoy the fragrance of the sacrifices, and it was considered that everything in this world could be got by the power of sacrifices. If certain oblations were made, certain hymns chanted, certain peculiar forms of altars made, the gods would grant everything. So Nachiketas asks by what form of sacrifice can a man go to heaven. The second boon was also readily granted by Yama who promised that this sacrifice should henceforth be named after Nachiketas.
