YV 6.5i

d Knee deep should he pile (it), when piling for the first time; verily with the Gayatri he mounts this world; navel deep should he pile (it) when piling for the second time; verily with the Tristubh he mounts the atmosphere; neck deep should he pile (it) when piling for the third time; verily with the Jagati he mounts yonder world. e After piling the fire he should not have intercourse with a woman of pleasure, thinking, 'I shall deposit seed in that which is no womb'; nor after piling for the second time should he have intercourse with the wife of another [3], nor after piling for a third time should he have intercourse with any woman whatever. In that he piles the fire, he deposits seed; if he were to have intercourse. he would be deprived of seed. Or rather they say, 'If he were not to have intercourse, there would be no offspring.' In that he puts down the two Retahsic (bricks), they support the seed of the sacrificer; therefore he should have intercourse, for the non-spilling of seed.' f Three seeds are there, father, son, grandson [4]; if he were to put down two Retahsic (bricks), he would cleave his seed; three he puts down, for the continuity of seed; the first Retahsic is this (earth), this (earth) is speech, therefore they see this (earth), they see speech speaking; the second is the atmosphere, the atmosphere is breath, therefore they see not the atmosphere, nor breath; the third is yonder (sky), yonder (sky) is the eye, therefore they see yonder (sky), they see the eye. With a Yajus he sets down this one [5] and yonder one, but with mind only the middle, to arrange these worlds, and also the breaths. g 'The sacrifice offered by the Bhrgus, the Vasus, accord our desires; of thee thus offered, enjoyed, may I here enjoy wealth,' he says; verily he milks thereby the song and the recitation.
