I do martial arts that follow the concept of qi (chi,ki) i wanna know is there a connection or association with Judaism like is there a Jewish outlook on it. According to Judaism is qi a legitimate concept.
Judaism does not have a "position" as to what types of excersize programs or meditations are "legitimate". Good health is certainly a halachic value. I have not been able to find any reason that ki is objectionable, and it certainly sounds interesting. If you find any rituals or rites, they should be investigated, but the basic idea of energies is not paganism.
