There is an exercise in We All Have Souls and I Think We Can Prove It that shows it is impossible to live in the physical world without harming other living things. In brief it asks you to consider a vegetable.
One point of the exercise is that we need to eat other living things to survive. When you eat the vegetable, feeding you becomes its sole purpose for existing. A carrot or stalk of broccoli that you eat doesn’t go on to make more carrots or broccoli. It’s finished, at least in the “bloodline” (seedline?) sense.
There are a lot of answers to what stops our magic. For this discussion let’s look at the magic we find in any practice that makes changes in our worlds and in ourselves. I include shamanism, witchcraft, conjure, martial arts, energy healing, and all the rest of the practices of soul reality in my definition of magic. Making changes on ourselves or on other parts of reality can be very difficult at any time. When our abilities are limited, it’s even harder.
Writers on this topic usually divide the ways we limit ourselves into two categories: fear and separation. Let’s take a look at each.
Several authors, including Mary Shutan, have written about the fear we feel. Mary discusses the question from a shamanic perspective. She looks at two kinds of fear: fear of death and fear of life.
