Sudama don't leave- Krishna is walking in the grass
Sudama: One afternoon after his nap I was bringing him a little rasagulla and some drink. The sun was going down when I started to enter his room, which faced the backyard. The whole room seemed purple and gold. There was a certain energy in the room. Srila Prabhupada was chanting and crying tears of ecstasy. Well, we didn't even have The Nectar of Devotion yet. I got alarmed, backed out of the room with the tray, went to Govinda dasi and said, "Govinda, what's happening? Is Prabhupada OK? Is he having a fit?" She said, "No, no. That's just Srila Prabhupada having a relationship with Krishna. That's Krishna consciousness." I said, "Wow!" I went back in five minutes later.
Srila Prabhupada was still there, and this time he stopped me from leaving. He said, "Sudama don't leave. I am crying because of the mercy of my Guru Maharaj. By his mercy I am allowed to see Krishna. I see Him right now over those grasses." Oh, man. It was so heavy that I started crying. He said, "Why are you crying?" I said, "Because you are so powerful and merciful. I have never met a soul like you." He said, "That is Krishna's arrangement."
