A human being is required to accumulate daivī sampat, or spiritual assets; otherwise, the next alternative, āsurī sampat, or material assets, will overcome him disproportionately, and thus one will be forced into the entanglement of different miseries of the material world. A sannyāsī should always live alone, without company, and he must be fearless. He should never be afraid of living alone, although he is never alone. The Lord is residing in everyone's heart, and unless one is purified by the prescribed process, one will feel that he is alone. But a man in the renounced order of life must be purified by the process; thus he will feel the presence of the Lord everywhere and will have nothing to fear (such as being without any company). Everyone can become a fearless and honest person if his very existence is purified by discharging the prescribed duty for each and every order of life. One can become fixed in one's prescribed duty by faithful aural reception of Vedic instructions and assimilation of the essence of Vedic knowledge by devotional service to the Lord.
(Srimad Bhagavatam-----2:2:25-----purport).

The idea is that the renounced order of life, after a frustrated life of sentiment in the material world, may be the stepping stone on the path of self-realization, but real perfection of the path of liberation is attained when one is practiced to depend fully on the Supreme Personality of Godhead, who lives in everyone's heart as Paramātmā. One may live in the darkest jungle alone out of home, but a steadfast devotee knows very well that he is not alone. The Supreme Personality of Godhead is with him, and He can protect His sincere devotee in any awkward circumstance. One should therefore practice devotional service at home, hearing and chanting the holy name, quality, form, pastimes, entourage, etc., in association with pure devotees, and this practice will help one awaken God consciousness in proportion to one's sincerity of purpose. One who desires material benefit by such devotional activities can never depend on the Supreme Personality of Godhead, although He sits in everyone's heart.
(Srimad Bhagavatam-----1:13:27-----purport).

Sometimes when we hear that great sages and devotees go to the forest and engage themselves in devotional service or meditation, we become surprised: how can one live in the forest and not be taken care of by anyone? But the answer, given by a great authority, Nārada Muni, is that such persons are well protected by the Supreme Personality of Godhead. Śaraṇāgati, or surrender, means acceptance or firm belief that wherever the surrendered soul lives he is always protected by the Supreme Personality of Godhead; he is never alone or unprotected. Dhruva Mahārāja's affectionate father thought his young boy, only five years old, to be in a very precarious position in the jungle, but Nārada Muni assured him, "You do not have sufficient information about the influence of your son." Anyone who engages in devotional service, anywhere within this universe, is never unprotected.
(Srimad Bhagavatam-----4:8:68-----purport).

Vāmanadeva asked Bali Mahārāja to go to the hellish planets, apparently just to show the entire universe how tolerant he was, and Bali Mahārāja did not hesitate to carry out the order. A devotee does not live alone. Of course, everyone lives with the Supreme Personality of Godhead, but because the devotee is engaged in His service, he actually does not live in any material condition. Bhaktivinoda Ṭhākura says, kīṭa janma hao yathā tuyā dāsa. Thus he prays to take birth as an insignificant insect in the association of devotees. Because devotees are engaged in the service of the Lord, anyone who lives with them also lives in Vaikuṇṭha.
(Srimad Bhagavatam-----8:21:32-----purport).

For a sannyāsī, the first qualification should be fearlessness. Because a sannyāsī has to be alone without any support or guarantee of support, he has simply to depend on the mercy of the Supreme Personality of Godhead. If one thinks, "After I leave my connections, who will protect me?" he should not accept the renounced order of life. One must be fully convinced that Kṛṣṇa or the Supreme Personality of Godhead in His localized aspect as Paramātmā is always within, that He is seeing everything and He always knows what one intends to do. One must thus have firm conviction that Kṛṣṇa as Paramātmā will take care of a soul surrendered to Him. "I shall never be alone," one should think. "Even if I live in the darkest regions of a forest I shall be accompanied by Kṛṣṇa, and He will give me all protection." That conviction is called abhayam, fearlessness. This state of mind is necessary for a person in the renounced order of life.
(Bhagavad-Gita-----16:1-3-----purport).

Kṛṣṇa, of course, means Kṛṣṇa and His confidential devotees; Kṛṣṇa is not alone. When we speak of Kṛṣṇa, "Kṛṣṇa" means Kṛṣṇa in His name, in His form, in His qualities, in His abode and in His associates. Kṛṣṇa is never alone, for the devotees of Kṛṣṇa are not impersonalists. For example, a king is always associated with his secretary, his commander, his servant and so much paraphernalia. As soon as we accept Kṛṣṇa and His associates as our preceptors, no ill effects can destroy our knowledge. In the material world the knowledge which we acquire may change because of the influence of time, but nevertheless the conclusions received from Bhagavad-gītā, directly from the speeches of the Supreme Lord, Kṛṣṇa, can never change. There is no use interpreting Bhagavad-gītā; it is eternal.
(Srimad Bhagavatam-----3:25:38-----purport).

A king is always accompanied by his ministers, secretaries and commanders, and Lord Viṣṇu is also accompanied by His followers—the demigods, great sages, saintly persons and so on. He is never alone. Consequently there is no question of the Lord's being impersonal. He is always Himself, the Supreme Personality of Godhead, and His associates are also persons. From the description given in this verse, Garuḍa appears to belong to the Kinnara planet. The inhabitants of the Kinnara planet have the same features as Garuḍa. Their bodily features are like those of a human being, but they have wings. The word gīta-kīrtiḥ indicates that the inhabitants of Kinnaraloka are very expert in singing the glories of the Lord.
(Srimad Bhagavatam-----4:30:6-----purport).
