There is a lot of info on energy work online. I personally don't care for it but I think the question is not whether it is professional or legal (there are plenty of people practicing such things). More whether you are open to trying it, if you are skeptical to start with. I like experimenting with many different things that are meant to regulate body and mind, attention, sensation etc. But I personally would not see a psychotherapist for these things even if I was very curious, just like I would not do meditation in therapy sessions (which I otherwise like and practice on my own and also like guided, given it's someone's style fits with me). I think it's normal to experience some anxiety about new experiences. I would say, if you are curious, give it a try and be mindful to stop if it's negative or your instincts suggests something weird around it.
