First the term energy manipulation as opposed to energy control.
Thinking in terms of manipulation creates a thoughtform of not only manipulating
but of being manipulated.
Second is the term subtle energy, the first law of thermodynamics is energy is neither created
or destroyed ONLY transformed. So whatever energy psi is has to be transformed according to
some description of personal energies and some reality of external energies.
Third dangers of self-hypnosis in the forms of empty-mind meditation, trance, and
any other thinking methods that put the subconscious mind in charge of the conscious mind summarized in two words; energy programming. If energy is not created or destroyed only transformed, every unit of internal and external energy carries some form of information. Memetics are self-organizing information structures. The mind that does not stay more organized by the consciousness than by memetics risks being controlled by memetics more and more systematically reducing the conscious mind of its control of the subconscious.
Please judge the merits of my post on knowledge. For objective knowledge must be greater than subjective opinion in order for any system of perception to be widely accepted on evidence of meta-analysis.
