Religious Mysticism

You get to choose between any of the 19 Variations of Religious Mysticism. Which one do you choose and why? What would you do with it?

This has been going around in my mind for a while, and I just wanted to ask everybody's opinion on which one is the strongest. Also, preferably, I want you all to tell me why you think it's the strongest (out of curiosity, of course). I think this question is intriguing and I'm genuinely surprised that nobody has asked this question.

This finally happened! Mysticism is now updated and is no longer an unclear pure form of Magic. Currently, Mysticism is not even magic at this point and was reformed by its actual meaning as the power to gain supernatural abilies via personal connection with the supernatural. Thus, there appeared Religions Mysticism as its expression based on faith and its three variations revolving around Taoism, Christianity and Shinto.

I would like to tell these changes are indeed great because they fit the primordial meaning behind the name as well as it makes some specific capabilities Mysticism originally lacked. Also, with its flexible system, it become a versatile power with potential for more variations to come by. I greatly appreciate these updates.
