Westla are you telling me that you think the power of the mind can cause the body to transform and shield off harm from smashing bricks with your hand, breaking iron bars over the head with speed etc?
Yes. Why is this any less believable than consciously being able to direct the flow of mystic energy?
Within 5 mins of me using Reiki my hands are very hot indeed and I won't have even tensed my arms or hands in any way what so ever.
Some people blush when embarrassed. They don’t do anything to make their face red, it occurs because their brain caused it to happen in response to a situation in which they felt uncomfortable. The brain can do many physical things. It might even be able to instruct pain sensors to shut off and tissues not to respond to injury. Obviously the martial arts masters believe they are directing energy to protect themselves, but isn’t it in the realm of possibilities that they have managed to control their brain instead?
Using chi on your penis for gains is probably not a good idea, as the results of doing so cannot be predetermined.
“Because Reiki is guided by the God-consciousness, it can never do harm. It always knows what a person needs and will adjust itself to create the effect that is appropriate for them.” from reiki.org
