Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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 by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
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.
