A question for the Chi / Ki practitioners
I'm not sure this is the right forum for this question - so moderators please feel free to move it to an appropriate area.
I'm interested to know what, if any, alternative explanations people have for the sensations that are often attributed to 'chi' - at least within tai chi practice.
On a personal level I have experienced an increase in warmth in my hands, and tingling / pins and needles type sensations, predominantly in the hands and arms but also travelling around the body, especially around the spine. Whilst I'm prepared to accept the traditional explanation that these sensations are a result of 'chi circulation' (I can hear the typing of insults already) I am curious as to what, if any, other theories can explain this effect.
