Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 3
एक एव चरेद्भिक्षुरात्मारामोऽनपाश्रय: ।सर्वभूतसुहृच्छान्तो नारायणपरायण: ॥ ३ ॥
eka eva cared bhikṣurātmārāmo ’napāśrayaḥsarva-bhūta-suhṛc-chāntonārāyaṇa-parāyaṇaḥ
The sannyāsī, completely satisfied in the self, should live on alms begged from door to door. Not being dependent on any person or any place, he should always be a friendly well-wisher to all living beings and be a peaceful, unalloyed devotee of Nārāyaṇa. In this way he should move from one place to another.
