Aitareyabrahmana 4.19

They undertake the Svarasāman days; these worlds are indeed the Svarasāman days. By the Svarasāman days they gained these worlds; that is why the Svarasāman days are called Svarasāman days. In that they undertake the Svarasāman days, they bestow a share in these worlds upon him. The gods feared the collapsing of those seventeen-fold [stomas]: 'Equal, as it were, are the stomas, unhidden as it were; may they not collapse.' They fortified them with all the stomas from below, and with all the pṛṣṭhas from beyond. In that the Abhijit with all the stomas is below and the Viśvajit with all the pṛṣṭhas is beyond, they fortify the seventeen-fold [stomas] on both sides for support, against collapsing. The gods feared that Āditya would fall down from the heavenly world; they wove him upward with five rays. The rays are indeed the divākīrtya [chants]: the Mahādivākīrtya is the pṛṣṭha, Vikarṇa is the brāhmaṇācchaṃsin's sāman, Bhāsa is the agniṣṭomasāman, both Bṛhat and Rathaṃtara are in the pavamāna [lauds]. Thus they weave Āditya upward with five rays for support, against falling down. When Āditya has risen, he should recite the morning litany; for this whole day is a Divākīrtya day. They should seize a victim for Sūrya, white with black marks, as an additional offering to the pressing-day victim; for this day has Sūrya as its deity. He should recite twenty-one kindling verses; for perceptibly this day is the twenty-first. Having recited fifty-one or fifty-two [verses], he inserts the nivid in the middle; he recites as many subsequent [verses]. A man has a hundred years of life, a hundredfold virility, a hundredfold sensory power; he thereby establishes him in life, in virility, in sensory power.
