Here’s an interesting quote by Neville Goddard:

“The mechanism of creation is hidden in the very depth of the subconscious, the female aspect or womb of creation. The subconscious transcends reason and is independent of induction.

It contemplates a feeling as a fact existing within itself and on this assumption proceeds to give expression to it. The creative process begins with an idea and its cycle runs its course as a feeling and ends in a volition to act. Ideas are impressed on the subconscious through the medium of feeling. No idea can be impressed on the subconscious until it is felt, but once felt-be it good, bad or indifferent-it must be expressed.

Feeling is the one and only medium through which ideas are conveyed to the subconscious.

Therefore, the man who does not control his feeling may easily impress the subconscious with undesirable states.

By control of feeling is not meant restraint or suppression of your feeling, but rather the disciplining of self to imagine and entertain only such feeling as contributes to your happiness. Control of your feeling is all important to a full and happy life. Never entertain an undesirable feeling nor think sympathetically about wrong in any shape or form. Do not dwell on the imperfection of yourself or others. To do so is to impress the subconscious with these limitations. What you do not want done unto you, do not feel that it is done unto you or another. This is the whole law of a full and happy life. Everything else is commentary.”
