One of the most necessary things to remember is that we cannot demonstrate life beyond our mental ability to embody. We give birth to an idea only from within ourselves. What we are, we put into our thinking. What we are not, we cannot put into it.
If we are to draw from life what we want, we must first think it forth into Life. It always produces what we think. In order to have success, we must first conceive it in our own thought. This is not because we are creators, but because the flow of life into manifestation, through us, must take the form we give to it, and if we want a thing we must have within ourselves the mental equivalent before we get it.
