" It is a Sufi contention that truth is not discovered or maintained by the mere repetition of teachings. It can only be kept understood by the perpetual experience of it. And it is in the experience of truth that the Sufis have always reposed their trust. Sufism is therefore not 'Do as I say and not as I do', or even 'Do as I do', but 'Experience it and you will know'. "
