Here’s an interesting quote by Neville Goddard:

“I say imagination creates reality, and if this premise is true then imagination fulfills itself in what your life becomes. Although I have changed the words, what I am saying is not new. But until imagination becomes a part of your normal, natural currency of thought, you will not act consciously.

Like breathing, this awareness must become so much a part of you that you will not turn to the left or the right to praise or blame anyone. When you know this presence it will not matter if you started life behind the eight-ball, or in a palace; as a poor, or a rich child; you will realize that life is always externalizing what you are imagining.

Lacking the knowledge of this principle, you can reproduce your environment – be it pleasant or unpleasant – forever and ever, as you feed your imagination on what your senses dictate. But knowing this principle, you can ignore the present, and untethered by the so-called facts of life, you can imagine the present as you desire it to be and feed upon your desire, rather than its omission.

Now, imagination cannot be observed as we see objects in space, for imagination is their reality. A thought that is not felt produces nothing. But a thought producing motor elements reproduces itself! Unless, of course you arrest your thoughts and revise them. Most of us, however, are not aware of what we are doing, so we do not observe our thoughts.”
