srakve drapsasya dhamataḥ sam asvarann iti nava pāvamānyo.
nava vai prāṇāḥ, prāṇān evāsmiṃs tad dadhāty
ayaṃ venaś codayat pṛśnigarbhā ity
ayaṃ vai veno.
'smād vā ūrdhvā anye prāṇā venanty avāñco 'nye, tasmād venaḥ.
prāṇo vā ayaṃ san nābher iti,
tasmān nābhis, tan nābher nābhitvaṃ prāṇam evāsmiṃs tad dadhāti
pavitraṃ te vitatam brahmaṇas pate, tapoṣ pavitraṃ vitataṃ divas pade,
vi yat pavitraṃ dhiṣaṇā atanvateti pūtavantaḥ prāṇās.
ta ime 'vāñco retasyo mūtryaḥ purīṣya ity, etān evāsmiṃs tad dadhāti

i. 20 (iv. 3). ‘They of the sounding deep have sounded at the rim’ are nine (verses ) for Soma the purifying; the breaths are nine; verily thus he places the breaths in him. ‘May Vena impel those born of Pṛśni’ (he says ); Vena is (this breath) here; above this here some breaths circulate (*venanti*), below others; therefore is it Vena; ‘the breath being here hath not feared (*nābheḥ*)’ (they say); therefore is it the navel; that is why the navel has its name; verily thus he places breath in him. ‘Thy strainer is outspread, O lord of holy power’, ‘The strainer of the scorcher is outspread in the expanse of sky’ and ‘What time the Dhiṣaṇās spread out the strainer’ (he says ); these breaths are connected with (the word) ‘strained’; those breaths below are connected with seed, urine, and excrement; them verily thus he places in him.
