I'm looking for some book(s) recommendations. I'm interested in the internal arts, so i'm looking to have a better theoretical grasp of the whole energetic interplay of our body and the cosmic forces. Where Is good place to start? I've been meditating for a few years already; I've done some energetic healing courses and I'm currently learning tai chi, so I have a little background on the subject. I was also looking into doing the Nathan Brine online course or Damo Mitchell's but maybe I'm getting ahead of myself. Maybe I should start by doing some general reading....   Thanks in advance
