Mysticism is the term used for the doctrine of being able to attain godliness by introspection and self-surrender. This is a pretty deep kind of doctrine, so let’s explore it a little deeper. Godliness, to those who believe in mysticism, is very hard to attain on earth. To them, “godliness” isn’t just being clean and living by a set of rules; it’s basically being one with their deity.
The most popular terminology for this in common words is “becoming one with deity”. This is practiced in a lot of older religions. Examples include Buddhism (all forms), Taoism, Daoism, and even early Christianity. Even Jews practiced this in their early days, and some branches of Judaism still practice mysticism in their daily lives, or try to.
A theory or doctrine according to which knowledge of God, of spiritual truth, of ultimate reality cannot be attained through reason, rational intelligence, or sense perception, but only through subjective experience, meditation, inner vision, etc.
