Reddit mentions of The Varieties Of Religious Experience: A Study In Human Nature

Read The Varieties of Religious Experience by William James

On the topic of religion in general, which is important to understanding Mormonism as much as any other religion, a few books would help:

The Outsider Test for Faith - John Loftus

What You Don't Know About Religion (but should) - Ryan Cragun
(he is an exmormon, and this adds to the interest for those of Mormon background)

The Varieties of Religious Experience - William James
(a classic)

I also have a somewhat short summary where I examine the claims of the Church:

Examining Church Claims

Good luck!

I didn't experience anything that Mystics and shamans haven't been experiencing for tens of thousands of years. I'll only get specific about my experiences with fellow Mystics, shamans. But I might consider getting specific with a skeptic who has read all the following books.
