Inayat Khan, Indian mystic and educator (d. 1927)
Inayat Khan Rehmat Khan (Urdu: عنایت خان رحمت خان

) (5 July 1882 – 5 February 1927) was an Indian professor of musicology, singer, exponent of the saraswati vina, poet, philosopher, and pioneer of the transmission of Sufism in the West. At the urging of his students, and on the basis of his ancestral Sufi tradition and four-fold training and authorization at the hands of Sayyid Abu Hashim Madani (d. 1907) of Hyderabad, he established an order of Sufism (the Sufi Order) in London in 1914. By the time of his death in 1927, centers had been established throughout Europe and North America, and multiple volumes of his teachings had been published.Inayat Khan's teaching emphasized the oneness of God (tawhid) and the underlying harmony of the revelations communicated by the prophets of all the world's great religions. His discourses treated such varied subjects as religion, art, music, ethics, philosophy, psychology, and health and healing. His primary concern was the mystical pursuit of God-realization. To this end he established an Inner School comprising four stages of contemplative study based on the traditional Sufi disciplines of mujahada, muraqaba, mushahada, and mu‘ayyana, which he rendered in English as concentration, contemplation, meditation, and realization.
