“In this form of spiritual transmission, the spirits meet in the world called calam al-arwah (the world of spirits) which is beyond calam al-ajsam (the material plane). Whoever takes knowledge through spirituality from a deceased Master in the Naqshbandi Way, is called both Uwaisi and Naqshbandi. That spiritual connection is as powerful and effective as the physical connection.”—The Naqshbandi-Haqqani Sufi Order of America: Sufism and Spirituality
