The Indian Sufi mystic and musician Hazrat Inayat Khan (1882-1927) was the very first teacher to bring Sufism -- the mystical heart of Islam -- to the Western world. Sufism is the religion of the heart and the Gathas are the teachings Inayat Khan gave to his students in America and Europe. They contain guidance on seven subjects: superstition, customs and beliefs, insights, symbology, breath, cultivation of the heart, everyday life and metaphysics. Clearly presented and easily accessible for the modern reader. The Gathas give a multi-faceted insight into the all-encompassing wisdom of Sufism which is perhaps more relevant today than ever before.
