The Lord is not like the mundane lord. The mundane master or lord never enjoys equally with his subordinates, nor is a mundane lord immortal, nor can he award immortality to his subordinate. The Supreme Lord, who is the leader of all living entities, can award all the qualities of His personality unto His devotees, including immortality and spiritual bliss. In the material world there is always anxiety or fearfulness in the hearts of all living entities, but the Lord, being Himself the supreme fearless, also awards the same quality offearlessness to His pure devotees. Mundane existence is itself a kind of fear because in all mundane bodies the effects of birth, death, old age and disease always keep a living being compact in fear.
(Srimad Bhagavatam--2:6:18--purport).

To anyone who has full faith in the Supreme Personality of Godhead and the spiritual master, all the import of the Vedic literatures is revealed. He does not have to seek separately; the yogīs who engage in devotional service are full in knowledge and renunciation. If there is a lack of knowledge and renunciation, it is to be understood that one is not in full devotional service. The conclusion is that one cannot be sure of entrance into the spiritual realm—in either the impersonal brahmajyoti effulgence of the Lord or the Vaikuṇṭha planets within that Brahman effulgence—unless he is surrendered unto the lotus feet of the Supreme Lord. The surrendered souls are called akuto-bhaya. They are doubtless and fearless, and their entrance into the spiritual kingdom is guaranteed.
(Srimad Bhagavatam--3:25:43--purport).
