Lord Krsna in Dvaraka enjoyed the pastimes of a perfect human being. Therefore, when He washed the feet of the sage Narada and took the water on His head, Narada did not object, knowing well that the Lord did so to teach everyone how to respect saintly persons. The Supreme Personality of Godhead, Krsna, who is the original Narayana and eternal friend of all living entities, thus worshiped the sage Narada according to Vedic regulative principles. Welcoming him with sweet, nectarean words, He addressed Narada as bhagavan, or one who is self-sufficient, possessing all knowledge, renunciation, strength, fame, beauty and other, similar opulences. He particularly asked Narada, "What can I do in your service?
Narada replied, "My dear Lord, this kind of behavior by Your Lordship is not at all astonishing, for You are the Supreme Personality of Godhead and master of all species of living entities. You are the supreme friend of all living entities, but at the same time You are the supreme chastiser of the miscreants and the envious. I know that Your Lordship has descended to this earth for the proper maintenance of the whole universe. Your appearance, therefore, is not forced by any other agency. By Your sweet will only, You agree to appear and disappear. It is my great fortune that I have been able to see Your lotus feet today. Anyone who becomes attached to Your lotus feet is elevated to the supreme position of neutrality and is uncontaminated by the material modes of nature. My Lord, You are unlimited -- there is no limit to Your opulences. Great demigods like Lord Brahma and Lord Siva are always busy placing You within their hearts and meditating upon You.
The conditioned souls, who have now been put into the blind well of material existence, can get out of this eternal captivity only by accepting Your lotus feet. Thus, You are the only shelter of all conditioned souls. My dear Lord, You have very kindly asked what You can do for me. In answer to this I simply request that I may not forget Your lotus feet at any time. I do not care where I may be, but I pray that I constantly be allowed to remember Your lotus feet."
By asking this benediction from the Lord, the sage Narada showed the ideal prayer of all pure devotees. A pure devotee never asks for any kind of material or spiritual benediction from the Lord; his only prayer is that he may not forget the lotus feet of the Lord in any condition of life. A pure devotee does not care whether he is put into heaven or hell; he is satisfied anywhere, provided he can constantly remember the lotus feet of the Lord. Lord Caitanya taught this same process of prayer in His Siksastaka, in which He clearly stated that all He wanted was devotional service, birth after birth. A pure devotee does not even want to stop the repetition of birth and death. To a pure devotee, it does not matter whether he has to take birth again in the various species of life. His only ambition is that he not forget the lotus feet of the Lord in any condition of life.
