One of the processes of surrender is that one should simply depend on Kṛṣṇa, convinced that He will give one all protection. That Kṛṣṇa will protect His devotee is a fact, and Nanda Mahārāja and the other inhabitants of Vṛndāvana accepted this very simply, although they did not know that the Supreme Lord Himself was present before them. There have been many instances in which a devotee like Prahlāda Mahārāja or Dhruva Mahārāja has been put in difficulty even by his father but has been saved under all circumstances. Therefore our only business is to become Kṛṣṇa conscious and depend fully on Kṛṣṇa for all protection.
(Srimad Bhagavatam----10:7:31----purport).

Why should one approach a person who is blind with wealth? Rather, one should depend on Kṛṣṇa, and He will give everything. All the members of our Kṛṣṇa consciousness movement, whether they be gṛhasthas or sannyāsīs, should try to spread the Kṛṣṇa consciousness movement with determination, and Kṛṣṇa will supply all necessities. The process of ājagara-vṛtti, the means of livelihood of a python, is very much appreciated in this regard. Even though one may be very poor, he should simply try to advance in Kṛṣṇa consciousness and not endeavor to earn his livelihood.
(Srimad Bhagavatam----7:15:15----purport).

A kṛṣṇa-bhakta has no desire for his own personal benefit. He is completely protected by the Supreme. Avaśya rakṣibe kṛṣṇa viśvāsa pālana. Bhaktivinoda Ṭhākura says that he is desireless because Kṛṣṇa will give him protection in all circumstances. It is not that he expects any assistance from Kṛṣṇa; he simply depends on Kṛṣṇa just as a child depends on his parents. The child does not know how to expect service from his parents, but he is always protected nevertheless. This is called niṣkāma (desirelessness).
(Sri Caitanya Caritamrta----2:19:149----purport).

One who desires nothing but Kṛṣṇa and who is not influenced by the process of jñāna-mārga (cultivation of knowledge) actually becomes free from ignorance. A first-class person is one who is not influenced by karma (fruitive activity) or yoga (mystic power). He simply depends on Kṛṣṇa and is satisfied in his devotional service.
(Sri Caitanya Caritamrta----2:19:150----purport).

The devotee should accept Kṛṣṇa as his supreme maintainer and master. He should not think that he is being protected by a demigod. He should depend only on Kṛṣṇa, considering Him the only protector. The devotee must be firmly convinced that within the three worlds he has no protector or maintainer other than Kṛṣṇa. (5) Self-surrender means remembering that one's activities and desires are not independent. The devotee is completely dependent on Kṛṣṇa, and he acts and thinks as Kṛṣṇa desires.
(Sri Caitanya Caritamrta----2:22:100----purport).

The purpose of the material manifestation is to give the conditioned soul a chance to attain liberation and return to the āśraya-tattva, or the Absolute Truth. Since everything in the cosmic creation is dependent on the āśraya-tattva—the creative manifestation or Viṣṇu manifestation—the various demigods an? manifestations of energy, the living entities and all material elements are dependent on Kṛṣṇa, for Kṛṣṇa is the Supreme Truth. Thus Śrīmad-Bhāgavatam indicates that everything is sheltered by Kṛṣṇa directly and indirectly. Consequently perfect knowledge can be had only by an analytical study of Kṛṣṇa, as confirmed by Bhagavad-gītā.
