I've been continuing my reading this last week of the works of Neville Goddard. This afternoon I came upon a passage that really seems to put his method on how to manifest into a nutshell. So here it is from his book Out Of This World (he suggests doing this just as you're going to sleep)...
"The first step in changing the future is desire; that is: define your objective-know definitely what you want. Secondly: construct an event which you believe you would encounter following the fulfillment of your desire-an event which implies fulfillment of your desire-something that will have the action of self predominant. Thirdly: immobilize the physical body and induce a condition akin to sleep-lie on a bed or relax in a chair and imagine that you are sleepy; then, with eyelids closed and your attention focused on the action you intend to experience in imagination-mentally feel yourself right into the proposed action-imagining all the while that you are actually performing the action here and now. You must always participate in the imaginary action, not merely stand back and look on, but you must feel that you are actually performing the action so that the imaginary sensation is real to you."
"It is important always to remember that the proposed action must be one which follows the fulfillment of your desire; and, also, you must feel yourself into the action until it has all the vividness and distinctness of reality. For example: suppose you desired promotion in office. Being congratulated would be an event you would encounter following the fulfillment of your desire. Having selected this action as the one you will experience in imagination, immobilize the physical body, and induce a state akin to sleep-a drowsy state-but one in which you are still able to control the direction of your thoughts-a state in which you are attentive without effort. Now, imagine that a friend is standing before you. Put your imaginary hand into his. First feel it to be solid and real, then carry on an imaginary conversation with him in harmony with the action. Do not visualize yourself at a distance in point of space and at a distance in point of time being congratulated on your good fortune. Instead, make elsewhere here, and the future now. The future event is a reality now in a dimensionally larger world; and, oddly enough, now in a dimensionally larger world, is equivalent to here in the ordinary three-dimensional space of everyday life. The difference between feeling yourself in action, here and now, and visualizing yourself in action, as though you were on a motion-picture screen, is the difference between success and failure."
"Experience has taught me to restrict the imaginary action, to condense the idea which is to be the object of our meditation into a single act, and to re-enact it over and over again until it has the feeling of reality. Otherwise, the attention will wander off along an associational track, and hosts of associated images will be presented to our attention."
Neville suggests doing this right as you're going to bed for the night, and continue to imagine your chosen short scene over and over until you drift off to sleep. Also, you will most likely need to do this night after night, until you reach the feeling of it becoming an actuality. He gives various examples of success stories in his books, some manifested their desire after only a few nights, others took several weeks of nightly imagining.
