Below are the best books we could find on Mysticism.

Mysticism is the experience or pursuit of joining with the absolute or Divine. It takes place across every religious and ethnic tradition worldwide and has emerged since the beginning of human existence. It has been described in various ways including “one with” or “thisness” and ideas around it have slight differences. Mysticism can come through discipline or practice, such as daily meditation; enhancement, such as a drug experience or guided journey; from a divine intervention, such as through voices or visions; or from a combination of these elements. Some famous mystics who have greatly influenced and guided others include the Buddha, Meister Eckhart, Eleazar ben Judah, St. Teresa of Avila, and Martin Luther.
