The easiest and most obvious way to formulate an idea is to visualize it, to see it in your mind's eye as vividly as if it were alive. You can see with the naked eye only what already exists in the external world; in a similar way, that which you can visualize in your mind's eye already exists in the invisible realms of your mind. Any picture, which you have in your mind, is the substance of things hoped for and the evidence of things not seen.
What you form in your imagination is as real as any part of your body. The idea and the thought are real and will one day appear in your objective world if you are faithful to your mental image. This process of thinking forms impressions in your mind; these impressions in turn become manifested as facts and experiences in your life.
