Here's a paper I wrote for Fr. Notebaart's Global Religions and Belief Systems (MIB 519) back in 2008 while working on my Master's. He's using it for a course on Ritual this spring and I was surprised that I did not immediately recognize it. It served primarily as a jumping off point for my favorite independent study of my HD program, which resulted in another paper, Seeking the Divine Light: Four Medieval Mystics.
“In mystic states we both become one with the Absolute and we become aware of our oneness. This is the everlasting and triumphant mystical tradition, hardly altered by differences of clime or creed. In Hinduism, in Neoplatonism, in Sufism, in Christian mysticism, in Whitmanism, we find the same recurring note, so that there is about mystical utterances an eternal unanimity which ought to make a critic stop and think, and which brings it about that the mystical classics have, as has been said, neither birthday nor native land.”
