I believe. There are most certainly energies among us that cannot be explained by science. Different people or cultures give them different names. But all civilizations throughout history seem to refer at one time or another to presence or power that is unseen. I've felt them. I've seen signs. A shadow where none should be cast, a bird following me, a warm breath of air on a cool day or a draft in a warm room, the gift of a melody, healing, or peace. Naysayers blame psychology, physiology or random theory. I blame no one; I'm grateful to the spirits.
