This is an excerpt from the Satapatha Brahmana, an ancient Sanskrit Vedic prose treatise on ritual, translated by Julius Eggeling in 1900. The passage belongs to the Brahmana genre — priestly commentary that explains the meaning and cosmological significance of Vedic sacrificial practice. The central concern is the homology between the year-long Gavāmayana soma sacrifice, the human body, and the cosmic being Prajāpati: how do the ritual's components correspond to and "enter into" the human being?
The text works through a precise anatomical mapping, assigning specific hymn-forms (stomas, defined by their verse count) to body parts: the nine-versed Trivrit is the head, the fifteen-versed Panchadasha is the neck, the seventeen-versed Saptadasha is the chest, and so on through belly, ribs, arms, back, and spine. Specific sacrificial days (Abhijit, Vishvajit, the Vishuvat solstice day) are identified with the ears, eyes, and breath of the nose. The passage culminates in the claim that the Supreme Self inhabits the year-sacrifice so constituted, and the sage who grasps this identity is liberated, seated "free from pain on the heights of the sun."
The distinctively speculative move here — typical of late Vedic Brahmana literature — is the insistence that ritual, cosmos, and body are not merely analogous but structurally identical, so that performing the sacrifice correctly is simultaneously an act of self-knowledge and cosmic maintenance.
