SB 11.6.19
vibhvyas tavamrta-kathoda-vahas tri-lokyah
padavane-ja-saritah samalani hantum
anusravam srutibhir anghri-jam anga-sangais
tirtha-dvayam suci-sadas ta upasprsanti
Translation:
The nectar-bearing rivers of discussions about You, and also the holy rivers generated from the bathing of Your lotus feet, are able to destroy all contamination within the three worlds. Those who are striving for purification associate with the holy narrations of Your glories by hearing them with their ears, and they associate with the holy rivers flowing from Your lotus feet by physically bathing in them.
Purport:
Srila Visvanatha Cakravarti Thakura states, anusravam guror uccaranam anusruyante: “One should hear about Krsna by hearing from the spiritual master.” The bona fide spiritual master describes the pastimes, potencies and incarnations of the Personality of Godhead to his disciple. If the spiritual master is bona fide and if the disciple is sincere and obedient, then the communication between guru and disciple is just like nectar, both for the guru and the disciple. Ordinary persons cannot even imagine the special pleasure experienced by the devotees of the Lord. Such nectarean speaking and hearing destroys all contamination within the heart of a conditioned soul, the primary contamination being the desire to live without serving Krsna.
The other nectar described here is caranamrta, the nectarean waters that bathe the Lord’s feet. Lord Vamanadeva bathed His own lotus foot by kicking a hole in the universal covering so that the sacred Ganges water washed His toes and fell into the universe. The Yamuna River also washed Krsna’s lotus feet when the Lord appeared on this planet five thousand years ago. Krsna sported daily with His boyfriends and girlfriends in the Yamuna River, and consequently that river is also caranamrta. One should therefore try to take bath in the Ganges or Yamuna.
Every morning in ISKCON temples, the lotus feet of the Deity of Krsna are bathed, and the water thus sanctified is also called caranamrta, the nectar of Krsna’s lotus feet. Srila Prabhupada taught his disciples and followers to come before the Deities each morning and drink three drops of the caranamrta from the Deities’ bathing.
In all these ways one can purify his heart and relish spiritual bliss. When one is fixed on the platform of spiritual bliss, then one does not take another birth in the material world. In this verse the word suci-sadah is significant: one must engage in the purified activities of Krsna consciousness. One must learn to serve the Lord from the bona fide spiritual master, whose instructions one should accept without speculation. Those who are attached to the phantasmagoria of this world sometimes concoct their own whimsical concepts of God. But only from the bona fide spiritual master can we get perfect and pure knowledge about the Supreme Personality of Godhead and devotional service to Him. Such knowledge may be found in all the books of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada.
