Yudhisthira Maharaja knew that Narada Muni is the supreme spiritual master of human society who can teach the path of spiritual liberation leading to the understanding of the Supreme Personality of Godhead. Actually, it is for this purpose that Narada Muni compiled his Bhakti-sutra and gave directions in the Narada-pancaratra. To learn about religious principles and the perfection of life, one must take instruction from the disciplic succession of Narada Muni. Our Krsna consciousness movement is directly in the line of the Brahma-sampradaya. Narada Muni received instructions from Lord Brahma and in turn transmitted the instructions to Vyasadeva. Vyasadeva instructed his son Sukadeva Gosvami, who spoke Srimad-Bhagavatam. The Krsna consciousness movement is based on Srimad-Bhagavatam and Bhagavad-gita. Because Srimad-Bhagavatam was spoken by Sukadeva Gosvami and Bhagavad-gita was spoken by Krsna, there is no difference between them. If we strictly follow the principle of disciplic succession, we are certainly on the right path of spiritual liberation, or eternal engagement in devotional service.
