The Supreme Lord, Śrī Kṛṣṇa, stated to Uddhava, “One who is actually wise, who knows the truth of the self and possesses transcendental insight, rejects this world of dualities and the so-called knowledge meant for facilitating enjoyment of it. He instead engages himself in trying to satisfy the Supreme Personality of Godhead, the master of all. This is pure bhakti-yoga. Transcendental knowledge is greater than such ordinary pious activities as chanting of mantras, but pure devotional service is greater than even knowledge.”
