Satsvarupa Goswami: I recall Prabhupada?s power as a preacher and self-realised devotee; and I remember the amazing fact that Prabhupada was constantly speaking Krishna conscious realisations?as he sat down for lunch, as he spoke to devotees in his room, or even as he went to sleep at night. His flow of devotional arguments shows that Prabhupada?s thoughts were deeply-felt convictions, and at the same time they were the exact conclusions of the scriptures. We also didn?t see much difference in Prabhupada?s expressions, whether he was in Australia, in Hawaii, Tokyo, or on his way to India. And so it was when you were with Srila Prabhupada, everywhere was Krishna-katha. But this was not Krishna consciousness within a bubble. You were always on the battlefield. Prabhupada?s philosophy was like Krishna?s speaking to Arjuna on the battlefield. ?Preaching means fighting,? he said, ?not an easy life.?
