Hridayananda Goswami: While Hridayananda Goswami was Prabhupada's secretary in Mayapur, he was pleased to see how Prabhupada liked to hear his own singing of bhajanas on the tape recorder. Even while working, Prabhupada played a tape, and when the recording stopped, he asked that the other side be played again. One day, in a very jolly mood while listening to his own singing of haraye namah krishna, which had full harmonium, drum, and karatala accompaniment and a strong rhythm, Prabhupada began to speak. "Just go everywhere and play this tape and dance." He motioned with his hands to show how the devotees should dance. "Go all around the world performing like this and people will be so much attracted that you will make a million dollars!" As the GBC secretary responsible for all of South America, Hridayananda Goswami usually served Srila Prabhupada in a mood of separation as he worked and travelled constantly on Prabhupada's behalf. He often enhanced his remembrance of Srila Prabhupada, however, by playing his tapes wherever he went. Serving in separation, he felt intensely close to Srila Prabhupada, as much as when he was personally with him, if not more so. Yet late at night after the demands of traveling, preaching, and managing, Hridayananda Goswami would put on a tape of Prabhupada singing and playing harmonium, and as the transcendental sound of Prabhupada entered his ears, Hridayananda felt even more increased feelings of loving reciprocation for Srila Prabhupada. Thus vani (service to the order of Srila Prabhupada) enhanced vapuh (service to the personal form of the spiritual master). And conversely, vapuh enhanced vani. Hridayananda Goswami, interview.
