That man who is houseless, who roves over the world like a mendicant who has the foot of a tree for his refuge, who observes the vow of silence, never cooks for himself, and tries to control his senses, is, O Partha, a Renouncer observing the vow of mendicancy.
अनिकेतः परिपतन् वृक्षमूलाश्रयो मुनिः। अपाचकः सदा योगी स त्यागी पार्थ भिक्षुकः॥
