I think having like-minded people around and getting together in person to practice or just talk or whatever can be great (and those people can be hard to find, but precious if you do), but I would really advise against joining a 'spiritual' group of any kind, no matter how benign it looks. That's all I can really recommend right now... The community aspect can be beneficial but as soon as spirituality starts to take on religious traits, which it often does when there's organized teaching going on, things can tend to go wrong. That said, I'm going to be taking a Qi Gong course soon and have no problem with that sort of thing, because I'm not joining anything. Courses =/= organisations. Just be careful.
