Reddit mentions of Mystics

What appeals to you about Daoism and Zen? What do you mean by "an eastern spiritual compass"?

It should be noted that Christianity has a rich history of mysticism within the bounds of orthodox belief, in the Eastern and Western churches alike. Although Christian theology proceeds from much different terms and assumptions than those of Daoism and Zen, there are interesting areas of overlap that can make the Gospel appealing to adherents of those philosophies.

I've personally found these books helpful for developing a deeper understanding of Christianity's mystical dimension:

• Roots of Christian Mysticism by Olivier Clement
  
  
• The Cloud of Unknowing
  
  
• Mystics and Zen Masters by Thomas Merton (Merton, a Catholic monk, was one of the most popular writers of Christian spirituality in the 20th century. Zen and Daoism fascinated him and he wrote much on the topic.)
