The mystery of Hu is revealed to the Sufi who journeys through the path of initiation. The more a Sufi listens to Saut-e-Sarmad, the sound of the abstract, the more his consciousness becomes free from all the limitations of life. The soul floats above the physical and mental plane without any special effort on man's part, which shows its calm and peaceful state; a dreamy look comes into his eyes and his countenance becomes radiant; he experiences the unearthly joy and rapture of wajad or ecstasy. When ecstasy overwhelms him he is neither conscious of the physical existence nor of the mental. This is the heavenly wine to which all Sufi poets refer, which is totally unlike the momentary intoxications of this mortal plane.
