Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 13
Sanskrit:
निर्भिन्नं तालु वरुणो लोकपालोऽविशद्धरे: ।जिह्वयांशेन च रसं ययासौ प्रतिपद्यते ॥ १३ ॥
ITRANS:
nirbhinnaṁ tālu varuṇoloka-pālo ’viśad dhareḥjihvayāṁśena ca rasaṁyayāsau pratipadyate
Translation:
When the palate of the gigantic form was separately manifested, Varuṇa, the director of water in the planetary systems, entered therein, and thus the living entity has the facility to taste everything with his tongue.
