A disciple was taught a practice by the Prophet Muhammed through which he experienced ecstasy. After some days he came bringing fruit and flowers which he offered to the Prophet, thanking him greatly and saying, "The lesson that you taught me has been of such great value to me; it has brought me such joy. My prayers, which used to last a few minutes, now last all day." The Prophet said, "I am glad that you liked the lesson but, please, from to-day leave it."
