Pir Zia Inayat Khan's account of the deep ecumenism of Sufism as evidenced in a variety of historical, literary, intellectual, and spiritual convergences. Drawing on the Qur'an, prophetic traditions, classical Sufi sayings, traditional stories, and verses from Arabic, Persian, and Urdu divans, Mingled Waters examines the inner teachings of Hinduism, Buddhism, Zoroastrianism, Judaism, Christianity, and Islam from the perspective of Sufi gnosis. In the rivers of all the world's revealed traditions the same water flows, the water of divine revelation. Mingled Waters peers into a handful of its sparkling drops.
