The unalloyed devotees of the Supreme Lord, who are totally surrendered souls, do not care when they leave their bodies or by what method. They leave everything in Kṛṣṇa's hands and so easily and happily return to Godhead.
(Bhagavad-Gita--8:23---purport).

The Lord is knowable only by one who is a surrendered soul. Herein Brahmājī, the greatest of all material living beings, acknowledges this truth. Therefore, the fruitless spoiling of energy by pursuing the path of experimental knowledge must be given up. One should gain knowledge by surrendering unto the Lord and by acknowledging the authority of the persons mentioned herein. The Lord is unlimited and, by the grace of the yogamāyā, helps the surrendered soul to know Him proportionately with the advance of one's surrender.
(Srimad Bhagavatam--2:7:43-45---purport).

The path of spiritual life is stated in the Vedas to be like the edge of a sharpened razor. A little inattentiveness may at once create havoc and bloodshed, but one who is a completely surrendered soul, always seeking protection from the Lord in the discharge of his entrusted duties, has no fear of falling into material contamination.
(Srimad Bhagavatam--3:9:24---purport).

At the present moment, who will be successful in the rigid performance of the many yoga rules and regulations? Moreover, perfection is attained only by those who are surrendered souls. Where there is no mention of the Personality of Godhead, where is there surrender? And where there is no meditation upon the Personality of Godhead, where is the yoga practice?
(Srimad Bhagavatam-3:21:7---purport).

One should depend only on the causeless mercy of the Lord for deliverance and not even slightly on one's own strength. That is the perfect position of a Kṛṣṇa conscious person. The Lord is everyone's friend, but He is especially friendly to the surrendered soul. The simple process, therefore, is that a conditioned soul should remain surrendered to the Lord, and the Lord will give him all protection to keep him out of the clutches of material contamination.
(Srimad Bhagavatam--4:7:30---purport).

Like a desire tree, the Lord fulfills the desires of one who takes shelter of Him, but one who does not take such shelter is distinct from the surrendered soul. One who takes shelter at the lotus feet of the Lord is favored by the Lord, regardless of whether such a person is a demon or a demigod.
(Srimad Bhagavatam---8:23:8---purport).
