As reality is a state of happiness, your desires too are a state of happiness and are thus fulfilled when such a state is maintained. Since such a state of happiness may only be produced by thoughts of an infinite likeness to that of the desire's fulfillment, it is thus necessary to think thoughts of your desire as if it has already been fulfilled in order for it to be fulfilled by your experiencing of a state of happiness matching its fulfillment.
Furthermore, the distance to the fulfillment of your desire thus becomes that of the degree of likeness of your present thought compared to the thought you would be thinking were the desire presently fulfilled and its corresponding emotional state. Ergo, as your thought and emotional state approaches infinite likeness to that of the desires's fulfillment, the desire is then being fulfilled.
