Sufism

When bored at work I have taken to reading The Mystics of Islam by Reynold A. Nicholson. The concepts and the prose presented by the Sufis are a constant wonderful maze. About half way through now and my religious vocabulary has expanded to include: monist, theosophy, and pantheism.

One of my favorite lines:
"I went from God to God, until they cried from me in me, 'O Thou I!'"
