śrī-uddhava uvāca
vadanti kṛṣṇa śreyāḿsi
bahūni brahma-vādinaḥ
teṣāḿ vikalpa-prādhānyam
utāho eka-mukhyatā
sri-uddhavah uvaca -- Sri Uddhava said; vadanti -- they speak; krishna -- my dear Krishna; sreyamsi -- processes for advancement in life; bahuni -- many; brahma-vadinah -- the learned sages who have explained the Vedic literature; tesham -- of all such processes; vikalpa -- of varieties of perception; pradhanyam -- supremacy; uta -- or; aho -- indeed; eka -- of one; mukhyata -- being most important.
In order to clearly establish the exalted position of bhakti-yoga, or pure devotional service to the Supreme Lord, Sri Uddhava requests Lord Krishna to identify the supreme among all processes of self-realization. Not all Vedic processes lead directly to the ultimate goal, pure love of God; some only gradually elevate the consciousness of the living entity. For the purpose of giving a general outline of the process of self-realization, sages may discuss the various methods of elevation. But when the time comes to ascertain the most perfect process, the secondary methods must be cleared from the path.
