"Light" is that Āditya. "Light" is indeed its finale. He who knows thus attains identity with him. In this way he addresses all the pṛṣṭhas with this sāman-finale. And these chanted sāman-finales amount to five twenty-five-fold [groups]. It is through these very finales that the hotṛ recites afterwards. Regarding this they say: "One should begin with the trunk first, and then with the head; the trunk is indeed first, then the head." But that would be just as if one were to fall into a pit, namely if they were to descend from the twenty-five-fold trunk to the nine-fold head. One must begin only with the head. All these deities indeed attend upon the chant, [saying:] "He will begin with me, with me, with me!" If he should begin with the head, he prospers through whichever deity is the deity of the head's beginning. If with the wing, he prospers through whichever deity is the deity of the wings' beginning. If with the tail, he prospers through whichever deity is the deity of the tail's beginning. If with the trunk, he prospers through whichever deity is the deity of the trunk's beginning. The other deities are excluded. But all the deities are indeed in the head: these are the Vasus,
