Hazrat Inayat Khan's classic books were among the first to bring Sufism to the West. They remain among the most important introductions Westerners have to the concepts of the ancient religious tradition. In Rassa Shastra , Khan shares his teachings on Sufi ideas about the spiritual and sacred purpose to sex and relationships and stresses "true union," one of the Sufi keys to perfection. He warns against the danger of misusing this most sacred of divine gifts and stresses that misunderstanding sex and sexual desire leads to the deepest problems between men and women.
Hazrat Inayat Khan (Urdu: عنایت خان ) (July 5, 1882 – February 5, 1927) was an exemplar of Universal Sufism and founder of the "Sufi Order in the West" in 1914 (London). Later, in 1923, the Sufi Order of the London period was dissolved into a new organization formed under Swiss law and called the "International Sufi Movement". He initially came to the West as a representative of classical Indian music, having received the title Tansen from the Nizam of Hyderabad but soon turned to the introduction and transmission of Sufi thought and practice. His universal message of divine unity (Tawhid) focused on the themes of love, harmony and beauty. He taught that blind adherence to any book rendered any religion void of spirit.
