Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 14
Sanskrit:
निर्भिन्ने अश्विनौ नासे विष्णोराविशतां पदम् ।घ्राणेनांशेन गन्धस्य प्रतिपत्तिर्यतो भवेत् ॥ १४ ॥
ITRANS:
nirbhinne aśvinau nāseviṣṇor āviśatāṁ padamghrāṇenāṁśena gandhasyapratipattir yato bhavet
Translation:
When the Lord’s two nostrils separately manifested themselves, the dual Aśvinī-kumāras entered them in their proper positions, and because of this the living entities can smell the aromas of everything.
