The works of Hazrat Pir-o-Murshid Inayat Khan are one of the great spiritual treasures of the world. At once deeply rooted in the Sufi tradition and strikingly original in insight and expression, Hazrats teachings remain as potent and meaningful today as they were when originally communicated a century ago. These teachings contain a message for every human mind and heart, and indeed for humankind collectively. The aim of this series is to provide the full set of Hazrats best-known teachings in a form that balances fidelity to his original words with sensitivity to the contemporary evolution of the English language.
