Not very long ago in Hyderabad there was a mureed, rather an intellectual pupil, and he liked to talk. His teacher was interested in his intelligent inquiries, and so he encouraged him to talk, whereas it is the custom in the East for the pupil to remain silent before his teacher. One day the teacher was in a condition of exaltation and his pupil as usual wanted to discuss and argue, which was not agreeable to the teacher at that time. He said in Persian, "Khamush", which means silence. And the pupil became silent; he went home and remained silent. And no one heard him speak after that, no one in the house nor outside; he never spoke anywhere.
