Srila Prabhupada Passtimes:51-Swamiji is there a stage in advancement

Later when I was a little more advanced to talk to him one-to-one and was alone with him in his room, I asked a personal version of the same question. I was thinking of my own bad habits and my attempt to get relieved of them. I said, "Swamiji, is there a stage in advancement where you don't fall down again?" He said, "Yes." That's all he said and I was very pleased to hear it. Actually, from the first night I saw him I broke all my bad habits or they went away by themselves. He and the chanting had a powerful effect on me.
