What Is Sufism?

If invited to offer prayers in a Church, a Mosque, a Synagogue, or a Hindu Temple, the Sufi is ready to do so, knowing that all people worship the same God, the Only Being, no matter what Name they use. Yet the Sufi's true House of Worship is the human heart, in which the Divine Beloved lives. Sufism is a religion for those who wish to learn religion from it, a philosophy for those wanting wisdom from it, a mystical path for any who would be guided by it to the unfolding of the Soul, and yet it is beyond all these things. It is the Light of Life, which is the sustenance of every soul.
