प्राणो वै ग्रहः, सोऽपानेनातिग्राहेण गृहीतः, अपानेन हि गन्धाञ्जिघ्रति ॥ २ ॥
prāṇo vai grahaḥ, so’pānenātigrāheṇa gṛhītaḥ, apānena hi gandhāñjighrati || 2 ||
Yājñavalkya replied: The Prāṇa indeed is the Graha. ‘Prāṇa’ here means the nose, from the context. It, the nose, is connected with air. ‘Apāna’ here means odour; it is so called because it always accompanies odour, for everybody smells with the nose odours presented by the air that is breathed in (Apāna). This is expressed by the sentence: For one smells odours through the Apāna.
