One who actually wants to be liberated from the entanglement of this material world and go back home, back to Godhead, is actually a mystic yogi. The words explicitly used here are yuktena bhakti-yogena. Those yogis, or mystics, who engage in devotional service are the first-class yogis. The first-class yogis, as described in Bhagavad-gita, are those who are constantly thinking of the Lord, the Supreme Personality of Godhead, Krsna. These yogis are not without knowledge and renunciation. To become a bhakti-yogi means to automatically attain knowledge and renunciation. That is the consequent result of bhakti-yoga. In the Bhagavatam, First Canto, Second Chapter, it is also confirmed that one who engages in the devotional service of Vasudeva, Krsna, has complete transcendental knowledge and renunciation, and there is no explanation for these attainments. Ahaitukiwithout reason, they come. Even if a person is completely illiterate, the transcendental knowledge of the scriptures is revealed unto him simply because of his engagement in devotional service. That is also stated in the Vedic literature. 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 yogis 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 realmin either the impersonal brahmajyoti effulgence of the Lord or the Vaikuntha planets within that Brahman effulgenceunless 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.
