Thoughts and emotions are pure energy; some higher and faster than others. When higher energies occupy the same field as lower energies, the lower energies convert to higher energies. A simple example of this is a darkened room that has lower energy than a room bathed in light. Since light moves faster than non light, when a candle is brought into a dark room, the darkness not only dissolves and disappears, but it seems magically converted into light. The same is true of love, which is a higher/faster energy than the energy of hate.
St. Francis, in his famous prayer, beseeches God: “Where there is hatred, let me sow love.” What he is seeking is the power to dissolve and ultimately convert hate to the energy of love. Hate converts to love when the energy of love is in its presence. This is true for you, too. Hate, directed towards yourself or others, can be covered to the life giving, love granting life force of intention. Pierre Teilhard de Chardin put it this way: “The conclusion is always the same: Love is the most powerful and still the most unknown energy of the world”.
