"Devotional service is such a powerful transcendental method that it surpasses all other methods of transcendental realization. The Lord says, therefore, that He lives neither in Vaikuṇṭha nor in the heart of a yogī, but He lives where His pure devotees are always chanting and glorifying Him. The Supreme Personality of Godhead is known as bhakta-vatsala. He is never described as jñānī-vatsala or yogī-vatsala. He is always described as bhakta-vatsala because He is more inclined toward His devotees than toward other transcendentalists. In Bhagavad-gītā it is confirmed that only a devotee can understand Him as He is. Bhaktyā mām abhijānāti: (BG 18.55) 'One can understand Me only by devotional service, not otherwise.' That understanding alone is real because although jñānīs, mental speculators, can realize only the effulgence, or the bodily luster, of the Supreme Personality of Godhead, and yogīs can realize only the partial representation of the Supreme Personality of Godhead, a bhakta not only realizes Him as He is but also associates with the Personality of Godhead face to face."
