You get high on love. What does this mean? There is a chemical reaction within the body caused by your thoughts and/or your interaction with higher energies. It is a bit of a paradoxical set-up, for you come into contact with these higher energies by opening yourself to them through the activation within the body of certain chemicals through your thoughts. You control the physical gateways to Higher Consciousness with those thoughts, but at times, by grace, Higher Consciousness enters the door, causing you to have the thoughts that bring you into awareness of the presence of Love.
Love is all around you. It is your basic make-up, but it is part of the perfection of the human body as a tool of earth school that your free will and your thoughts control your awareness of your role as both student and soul.
