Ecstasy manifests in various aspects. Sometimes a Sufi may be in tears, sometimes a sigh may manifest; sometimes it expresses itself in Raqs, motion. All this is regarded with respect and reverence by those present at the sama assembly, as ecstasy is considered divine bliss. The sighing of the devotee clears a path for him into the world unseen, and his tears wash away the sins of ages. All revelation follows the ecstasy, all knowledge that a book can never contain and that a language can never express, nor a teacher teach, comes to him of itself.
