Reddit mentions of Shamanism and the Psychology of C.G. Jung: The Great Circle

Sucking bad spirits into a stone is actually a shamanistic practice in some cultures, I'm not sure if it's a south american thing, or a siberian thing. I took an intrest in shamanism years ago, but I'm more of a lurker here. That being said there is some not so good info out there on the subject, and if you are going to pursue it you should be careful about where you get your influences. I really liked this books approach to the subject

All that aside, if you are really struggling, than I suggest that you make use of your creative mind and apply it to ritual. What I am suggesting is that, in your own life you have had some pretty positive influences, and positive energy radiates. If there is some action, or thought that you can have that will center you in your most positive self then you should do that. Maybe you have a memory of your dad when you were both happy doing something, and now would be a good time to do that again. He is survived by you, and if you survive, I imagine you will want the best parts of you to survive, and the rest to.. well not.
