Srimad-Bhagavatam: Canto 1 - Chapter 1 - Verse 14

Sanskrit:

परिश्रान्तेन्द्रियात्माहं तृट्परीतो बुभुक्षित: ।स्‍नात्वा पीत्वा ह्रदे नद्या उपस्पृष्टो गतश्रम: ॥ १४ ॥

ITRANS:

pariśrāntendriyātmāhaṁtṛṭ-parīto bubhukṣitaḥsnātvā pītvā hrade nadyāupaspṛṣṭo gata-śramaḥ

Translation:

Thus traveling, I felt tired, both bodily and mentally, and I was both thirsty and hungry. So I took a bath in a river lake and also drank water. By contacting water, I got relief from my exhaustion.

Purport:

A traveling mendicant can meet the needs of the body, namely thirst and hunger, by the gifts of nature without being a beggar at the doors of the householders. The mendicant therefore does not go to the house of a householder to beg but to enlighten him spiritually.
