Learned to become silent, Prabhupada said, “Stones are silent for millions of years
Danavir Goswami: Two ladies in their fifties asked if they could see Srila. Prabhupada. I was the temple president, so I brought them to see him. They were very respectful but didn’t know what to say. There was silence. Finally one of them said, “Swamiji, we have been meditating for the last twenty years.” They thought that Prabhupada would be impressed, but he said, “What have you achieved by your meditation?” The lady thought for a moment and said, “We have learned to become silent.” Prabhupada said, “Stones are silent for millions of years. To become silent is not a very great accomplishment.” That set the mood for that discussion.
