“There are four sects of worshipful devotees of the Lord, and the chief amongst them are the Brahma-sampradaya, Rudra-sampradaya and Sri-sampradaya, descending directly from Lord Brahma, Lord Siva and the goddess of fortune, Laksmi, respectively. Besides the above-mentioned three sampradayas, there is the Kumara-sampradaya, descending from Sanat-kumara. All of the four original sampradayas are still scrupulously engaged in the transcendental service of the Lord up to date, and they all declare that Lord Krsna, Mukunda, is the Supreme Personality of Godhead, and no other personality is equal to Him or greater than Him.”
