apparently from the links you gave, soul is a metal creation, a word given to an abstract idea that one must identify with because of outside stimuli (i.e. being TAUGHT what it is), an idea that is transmitted over paper...and at BEST not one with much solidarity (as exposed in your links pointing out differences in use).

CHI on the other hand is tangible. something you can manipulate and USE. have you ever experienced chi? have you ever used it? have you ever done anything with it? have you ever consciously manipulated it?

the difference between STUDYING an idea like SPIRIT and SOUL from a christian perspective is that at most times that all you can do. you can THINK about god, but not manipulate him, you can THINK aout spirit but not manipulate it at WILL. this allows for a "interpretational" perspective on the individual level. meaning: since noone can really get into your relationshp with waht you believe, you are RIGHT no matter what they say, cuz all in all, no one can prove you wrong. it also allows for interpretation of OTHER (e.g. your association between holy spirit and chi) based on nothing more than your relationship with the FAMILIAR (holy spirit) to the UNFAMILIAR (chi) without even bothering to ATTEMPT to understand it. this is the arrogance of christian and western thought. the belief that without understanding (by means done WITHIN said unfamiliar system) you can equate something that is totally foreign to you.
