Where would internal alchemy and meditation practice fall into this categorization? I will assume it as part of daojiao.

>engaging with Daojiao does require faith in unseen and scientifically unverifiable things like deities and transcendents. (Which does not make Daojiao incorrect, only faith-based.)

Admittedly, starting internal alchemy is somewhat faith based. It took some suspension of disbelief (and youthful optimism) to consider the John Chang videos (Neikung Power and John Chang - Using Chi to set things on fire). As well, to consider the anecdotes throughout many mystic traditions and come to some consensus about their reality. For example, things from Autobiography of a Yogi, or Kosta Danos's books, Magus of Java: Teachings of an Authentic Taoist Immortal and Nei Kung: The Secret Teachings of the Warrior Sages, or in Opening the Dragon Gate: Making of a Modern Taoist Wizard.

Rather than looking at it as scientific evidence I consider it in the same way a historian would. We have a few first hand accounts of amazing phenomena. A ton of anecdote which convinced me to try things out. So, in a sense, this is faith. However, as you practice and experience things it is less based on faith and more based on experience. I am not claiming to have some ability that takes the Randi prize, but you have enough small experiences that you then believe there is something more and something worth training for.

My goal in training is to entirely take away the faith based aspect of internal alchemy. If at the end of my life I've achieved nothing reproducible, I'll come out and say that. If I have though, I would love to demonstrate it, and study it to an extent, so that others may practice without having to believe in what science doesn't support. I am actually amazed how militant some people can be about science based evidence when there are so many major blindspots in science. There is a lot we don't know and it is worth investigating what is possible. How amazing would it be to have a religion based on verifiable results? Spiritual development that develops an actual spirit? This is my dream, it would put so many of the current institutions in the dust.

Google up "Nei Kung" and read this book for an introduction to the martial arts aspects. There are also a couple of mediation books translated by Charles Luk which relate to the Toaist philosophical context. Also, Wilhelm Riech has some interesting theories - not to mention his life is an example of Western bias against the subject. For Indian as opposed to Chinese, look up kundalini meditation.

For occult sources, the OP already metioned a couple, plus there are the obvious mentions for Aleister Crowley in the blog post.

Currently I am studying The Secrect of the Golden Flower which I found an excellent copy of at my local bookstore. Once you go through this and get the gist of what the practice entails you'll find all sorts of interesting findings in neuroscience as well.
