"In Śrīmad-Bhāgavatam (2.2.5) there is a very nice verse stating that a devotee should always remain dependent on the mercy of the Supreme Lord and that as far as his material necessities are concerned, he should be satisfied with whatever is obtained without endeavor. In this regard, Śukadeva Gosvāmī advised that a devotee should never approach a materialistic person for any kind of help. As far as one’s bodily necessities are concerned, one can pick up torn clothing from the street, take fruits offered by trees, drink water from flowing rivers, and live in a mountain cave constructed by nature herself. Even if one is unable to do all these things, he should nonetheless completely depend on the Supreme Lord, understanding that since the Lord provides everyone with food and shelter, He will never fail to care for His devotees who are fully surrendered unto Him. In any case, the devotee is always protected, and therefore he should not be at all anxious for his maintenance."
