In the system I use it is subconciousness that does the work. Our personal subconciousness is connected to the universal subconcousness, thus when you imbed a thought in "yours" it manifests "out there". Do imbed that thought or idea you need to use suggestion, be subtle, be suave.
Subconciousness doesn't like to be hit head on. You walk up to it side on, turn your head slightly and offhandedly remark "I've got a new car", "Yeah, oh cool, I'll see to it." is the reply. Suggestion can be done in various ways, affirmations, visualisation, whatever... But the emotion or feeling about the suggestion is very, very important. If you walk up to subconciousness with fear in your heart and ask for something it'll sense it. I'd almost say it's like training an animal, they know how you're feeling and they'll respond accordingly.
This is A method, I'd like to hear your thoughts on it...
