They spake, 'Let us gather together food for him: therewith we will appease him!' They gathered for him that food, the Sântadevatya, and thereby appeased him; and inasmuch as they thereby appeased (sam) the god (deva), it is called Sântadevatya;--Sântadevatya, doubtless, is here called mystically 'Satarudriya,' for the gods love the mystic. And in like manner does this Sacrificer now bestow upon him that highest form, immortality. Flaming he there stands, longing for food. He gathers for him that food, the Sântadevatya, and thereby appeases him.
