When you are moved to use negative emotion acknowledge the thought then flip your coin over to the positive spectrum of imagination. The longer you permit your consciousness to dwell in negative emotion the more power you give to it which permits more darkness to flow through you. Each emotion is the result of the images within the mind. A child of light wills only the imaginations of the positive mind into the universe. Will only positive thoughts.
Imagination is the key.
Emotion is the tangible or physical manifestation of the intangible imagination. Imagination is the primary manifestation of mental activity. These images are many. The ones you choose, you then call thought. The positive imaginations are where our consciousness must dwell to have your minds and hearts parallel with the will of God.
