2set thee up', he says; Dyutana Maruta was wont to set up the Udumbara (post) of the gods; verily [4] by him he sets this (post) up. 'Thee that art winner of Brahmans, winner of nobles', he says; that is according to the text. 'With ghee, O sky and earth, be filled', (with these words) he sacrifices on the Udumbara (post); verily with moisture he anoints sky and earth. He makes it run right to the end; verily completely does he anoint the sacrificer with brilliance. 'Thou art of Indra', (with these words) he puts down the covering, for the seat has Indra as its deity. 'The shade of all folk', he says, for the seat is the shade of all folk. (A roof of) nine coverings [5] should he fix for one who desires brilliance, commensurate with the Trivrt Stoma; the Trivrt is brilliance; verily he becomes brilliant; one of eleven coverings (he should fix) for one who desires power; the Tristubh has eleven syllables, the Tristubh is power; verily he becomes powerful. (A roof of) fifteen coverings (he should fix) for one who has foes; the thunderbolt is fifteenfold; (verily it serves) for the overcoming of foes. (A roof of) seventeen coverings (he should fix) for one who desires offspring- Prajapati is sixteenfold. (verily it serves) to gain Prajapati. (A roof of) twenty-one coverings (he should fix) for one who desires support; the Ekavinça is the support of the Stomas; (verily it serves) for support. The Sadas is the stomach, the Udumbara is strength, in the middle he fixes (the post) of Udumbara wood; verily he places strength in the midst of offspring; therefore [6] in the middle they enjoy strength. In the world of the sacrificer are the southern coverings, in that of his foe are the northern; he makes the southern the higher; verily he makes the sacrificer higher than the man who does not sacrifice; therefore the sacrificer is higher than the man who does not sacrifice. He fills up the crevices, for distinction; therefore people depend on the forest. 'May our songs, O lover of song', he says; that is according to the text. 'Thou art the string of Indra;. thou art the fixed point of Indra', he says; for the Sadas has Indra for its deity. Now the knot which he first ties, if he were not to unloose it, the Adhvaryu would perish through suppression of urine; therefore it must be unloosed.
