"The perfectional stage of spiritual life, which one can experience even while being in the material world, is described by Lord Kṛṣṇa in the Twelfth Chapter of the Bhagavad-gītā. There it is said that one who is not envious of any living entity, who is friendly, merciful and detached from material possessions, who is situated in his pure identity, without any false conception of the body as the self, who is equipoised in both happiness and distress, who is forgiving, always satisfied, always engaged in devotional service, and always surrendered unto the Supreme Lord with his body and mind—such a devotee is very dear to Kṛṣṇa. A devotee who never gives trouble to any living entity, either by his body or his mind, who is never affected by material distress and happiness, and who is never angry or pleased with anything material is very dear to the Supreme Lord. He who is never dependent on anyone in this world, who is completely surrendered to the Supreme Lord, who is purified, expert, neutral, free of pain, and aloof from any material endeavor which requires too much attention—such a devotee is also very dear to Lord Kṛṣṇa. A person who is never subjected to material happiness or hatred, lamentation or ambition, who is aloof from all materially auspicious and inauspicious activities, and who is fully devoted in Kṛṣṇa consciousness—such a devotee is very dear to Lord Kṛṣṇa. A devotee who treats equally a so-called enemy and a so-called friend in the material world, who is not disturbed by heat or cold, who is without any attachment, who is equally situated when respected or insulted, who is always grave, satisfied in any condition of life, without any fixed residence, and fixed in Kṛṣṇa consciousness—such a devotee is very dear to Lord Kṛṣṇa. Even if one is not situated in the transcendental position, still, if he approves the transcendental life described here, he also becomes very dear to Kṛṣṇa.
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."
