Do you cast spells? Deliver incantations? Can one do this without believing in magic?
Seriously, many of the "spells" are quite good psychologically, because they use analogy and mental tricks to alter behavior.
For example, there is an apple banishing spell
which really is just an exercise in focusing on a bad habit to rid yourself of such. One focuses the habit and its effects into an object and burins the object, and salt is added so the habit/discomfort is "neutralized". When you bury the object, you are seeing it go into the ground, and when you want to do this habit, your mind remembers it's in the ground therefore it's easier to break.
I think prayer works much the same, psychologically. Although one is praying to some "other", it's really just focusing your intention and having your mind act accordingly...
as in: "dear God, please deliver me from smoking"... the person has already decided they want to quit, and when they light up they are focusing on the negative aspects of smoking... so they are already in the mindset to quit.
It's mind trickery which helps!
A great example using straight psychology... there is a beautiful documentary called Phantoms in the Brain
. There is a man with severe phantom pain from a hand he no longer has.
It feels to him as if his fist is clenched so hard and continues to clench without relief, clenching harder and causing great pain. A box was created with a mirror on one side. The patient slid his hand into the box, and it looked like he had two hands. Cognitively the man knew the other hand was a reflection, but it was enough that when he clenched and unclenched the fist, then opened the hand wide, his brain sent the signal that the phantom hand was unclenched as well and he found relief. Now all he has to do is use the box if the pain gets to him.
If I have a trouble which caused me distraction through the day, I decide to only allow myself to think about it at certain times. Since I am set to think about this at noon and again at 4, when my mind drifts there I simply tell myself, OK, I'm thinking about that at noon, so I can do this now. Then at noon I think about it till it's out of my system and go on. It's playing with the beautiful mind....
