Thanks for the reassurance. Energy that is not visible to the naked eye is as real as the microscopic diseases we cannot see.
Right now I do yoga , qi gong, and pilate. The qi gong has circular exercises that center my energy. Pilate also centers my energy to my stomach or chi. The yoga and asian arts have great breathing and visualization techniques, eg: circling your hands as if holding a large ball.
Yoga requires that we sleep with our head facing North. This might be similar to feng shui, which I have not studied yet, but have skimmed some books, about the placement and direction of everything.
