Subtle energy appears to be magical to most. Like magicians, those skilled in subtle energy work create amazing results without you knowing how they did it. And like magic, subtle energy work can be learned. We may each be viewed as a conduit for many different kinds of energy. We take in air, water, food, light, sound, heat and stimulation from our five senses. Additionally we receive other input from the natural world and psycho-spiritual energies of a subtle nature. We as humans have the capacity to process these energies because our anatomy is more than just the physical body that we walk around with. Subtle energy is considered to be any energy that is not one of the four forces of nature: weak force, strong force, electromagnetic force and gravitational force. It can be the energy we experience after vigorous exercise or the feeling we get when someone we feel strongly about looks right at us. Your intuitive feelings are a form of subtle energy as are your thoughts.
