What is subtle energy?
Generally speaking, subtle energy is the term used for various energetic phenomena that are not formally recognized as one of the four known fundamental forces. These forces are used to describe physical laws. There is gravity, color force, electromagnetism and weak nuclear force. "Qi", "prana" and "kundalini" are terms that represent forms of subtle energy that cannot usually be detected using conventional scientific instruments. Science tells us that we live in a virtual ocean of invisible fields of influence that affect our everyday lives in profound ways, yet we have little or no conscious awareness of them. The realities of subtle energy have been known for centuries, and are now slowly making their way into modern science.
