Objects possess properties. Some of them are easily discernable, others are escape immediate explanation. This is where creativity comes into play; How do you explain some some of the apparent effects of one object on another. Enter: the magick of thought. Every explanation manifests at the very least in the ideal realm, no matter how wild. Using this principle you can imbue properties into an object. The more conviction you have in your imagined property the more it will manifest in your conception of it on the ideal plane. Will that energy make it to the material plane? Who knows? But all things that exist materially, exist first as an idea.
