My sister practice tai chi with a good teacher :)

There can be various definition of qi, but when it get strong, it can be felt physically into the body, runing through meridians, but its also a metaphysical concept related to life energy, and related to breathing.

I think some teacher dont speak about it too much either not to look too crazy or make student too much seeking for supernatural things, and just do the practice with breathing, chi qong, tai chi to emulate this life energy until it can get to levels where it can be felt, i think rushing those things is not very good idea for responsible teachers anyway.

I didnt read that much jung, i know some of the broad concept, i know he travelled to india and wrote about kundalini, and made parallels between chakras and psychology, but lot of his works is not published too much, because he wanted to stay in freud line of scientific basis.

There is psychologist named james hillman who is interesting too in the study of depth psychology, he is the one who made the comments in gopi krishna book.

But still i think psychologist are too focused on therapy, and rarely see subconscious activity as a positive thing to study, or they become discredited in the academic world.

Taoist or budhist study this with a better angle, and go for shamless radical subjectivity , without having to tie themselves into axioms and thesis for the sake of clinical therapy, which is the only broad interest for the mass, and source of income for psychologists in occident.

Freud set the line very firmly about role of psychology as therapy, and curing disease with methology in sort that psychologists dont become spiritual gurus.

But its still bit a shame science doesnt study this stuff of subconscious more like the budhists or taoists.
