There was a sufi master Jabbar. He had a unique way of teaching. Whenever any of his pupils used to visit him with descriptions of divine visions and trances, he started talking nonsense with a vehement speed and kept continuously talking until all his pupils got bored and all their pride in visions and trances dropped out.
A profound silence used to follow his gibberish as it used to force out the chattering monkey minds of pupils. Jabbar was a mysterious person and never explicitly talked about his methods but they were uniquely effective and they did transform his pupils. His indirect message was that all your talk about visions, trances and spiritual experiences is rubbish. It’s gratification of ego which always wants to accomplish something. The effort is always ego’s effort. Transcendence of ego happens when all effort drops. But effort can’t drop until everything has been tried. Gibberish exhausted the minds of pupils and made them silent, peaceful and blissful. Whether it was a transmission of spiritual power along with the nonsensical words of Jabbar, whether this story is true or fictional; I honestly don’t know. But I am fond of the idea behind this word. I heard this story in one of the spiritual talks by Osho. I love it.
