chi is the human life force, the energy that animates your physical body, the reason you run on electromagnetism but dont plug into a wall... and you literally pull it into your body out of thin air every time you breathe.
relax your entire body.
take a deep breath, slow from the bottom of your stomach.
at the top of your breath, hold it.
clench kegel/anal muscle.
hold it for 7 secs.
release kegel/anal muscle.
breathe out as slowly as possible.
those energy pulses you feel in your body, that is chi.
and it doesnt carry with it psychic powers. but it does carry the ability to get your human vessel functioning at 100% capacity, which includes abilities that some would perceive as "supernatural" when really it's just having access to a more primal level of reality by possessing higher frequencies of energy.
an analogy: it's like having a broken button on your tv remote. the mute button may not work, the volume button may get stuck sometimes, but you can still change the channel, and you can still turn the tv off and on, etc
same thing with chi/life force... your mind and body may work on a basic level, but other fundamental abilities may be impaired.
