The Vajapeya Ascension Rite

"'May gain of food accrue to me'. (He further says) 'May these two, heaven and earth, of universal form' -- for, Prajapati [soul of the universe] is these two, heaven and earth. 'May father and mother come to me' -- for, Prajapati is both father and mother. (He says) 'May soma come to me to (confer) immortality'; for, Prajapati is soma. With these, he touches his own belly because it is there that the food settles."

To win the soma, he must first sacrifice its ingredients in the fire pit or kunda.

"'May my life prosper through (this) sacrifice; let my vital air prosper through (this) sacrifice; let my eye prosper through (this) sacrifice; let my ear prosper through (this) sacrifice; let the backside of my body prosper through (this) sacrifice; may the sacrifice prosper through (this) sacrifice." He who performs Vajapeya is winning Prajapati."

The Sacrificer must next climb the yupa pole as if climbing to the summit of Mt Meru - Indra's svarga or heaven.

"Then the wooden scaffold (ladder) is set ready. With that he ascends the yupa. In this manner, he ascends northwards...One should climb only northwards, for the north is the direction of human and it is (the quarter) that belongs to the Yajamana. So he climbs only northwards. [toward the pole star that marks the summit of Meru.]

"While about to climb the yupa, he addresses his wife, 'Come wife, let us ascend to the sky'. She replies 'Let us ascend.' Climbing this yupa, he feigns to be climbing to the heavenly world; because he has won the heavenly world (by the Vajapeya)."

"He ascends (thinking) 'We have become Prajapati's children". He who performs Vajapeya does indeed become Prajapati's child. He touches the wheat (on the top of the yupa, saying) 'We have reached to the light, O gods!' He who performs Vajapeya indeed, reaches the light. And why he touches the wheat is because he who performs Vajapeya wins food [soma]. Having gone to that (supreme) state and having won the heavenly world, he has won this food. So he contacts it and puts it into himself. With that (wheat dough) he smears his belly because it is there (in the belly) that food settles.
