As there is a single philosophic self-help system, a single background for all religions - there is probably also a singular approach to energy and an unexhaustible source (or several permutations) of energy for use. All based on this same central energy.
A Nathan Stubblefield found one (not well documented) variety of it from the earth.
Tom Bearden seems to have stumbled onto how to make this universal free energy available to any.
If there is any connection between the philosophical rules and the practical rules - that is another question. However, the question has already been raised in "The Secret".
