Greetings..
There are two sides to this story, for me.. Hard science on one side and myth on the other.. Science (physics) indicates no restriction on the “possibility” of such magical feats as described in previous accounts, i simply have very little evidence of such.. Myth, on the other hand, like someone else said, appears to be greatly embellished accounts of someone’s well-disciplined feats..
From my own experience, Qi is a multi-faced phenomenon.. it is easy enough to accept the notion that there is a unifying and all-pervasive force that permeates all things, that is the basic building block of existence as we know it.. science calls it “energy”.. that everything is energy, energy that vibrates at frequencies manifesting everything form light to solid rock.. energy vibrates at frequencies that produces matter and then animates it (life).. it maintains patterns (identities) and can be controlled by consciousness.. So, ultimately, we have the ability to control energy.. but, very little evidence that anyone can consistently achieve such control as necessary to effect such feats as described here..
I have, in the past, recounted several experiences that assure me that there is the potential for a human to discipline themselves to acheive amazing feats.. i will share one more.. My mentor will take a standard 16 oz. styrofoam 7-11 coffee cup and turn it upside down, place it on the ground and, stand on it with one foot.. and, not crush it (he weighs +/- 125-130 lbs.).. personally, i have destroyed hundreds of these cups trying to do the same (yes, i drink my share of 7-11 coffee..).. when i ask him how he does this he says, “i just make myself light”… subsequent discussions with other well-disciplined QiGong people, have indicated that he was able to tune his “frequency” with the cup’s.. which is why i once heard him say, “i can’t crush myself”.. anyway, take it for what it’s worth..
I think that the ancestors recognized the amazing feats of well-disciplined people and not being able to understand how they were done they assigned a label and description that satisfied their limited intellect relative to empirical science..
Qi, from my own perspective, is the combined effect of many systems and aspects of our physical and energetic being.. it is the “effect” that appears mystical, not the mechanics or discipline.. the mystic quality is only assigned by those that lack the discipline or conceptual ability to acheive that level of accomplishment.. something is “mystical” only by comparison to someone’s range of experiences.. while some people have great depth of experiences in this type of experience, others don’t and, so.. they find themselves at odds..
Lack of evidence is not evidence of non-existence.. it is a limitation on our current ability to measure or quantify a particular theory.. it simply means the theory stands as theory until conclusive evidence can prove or disprove it.. Cutting-edge particle physics leads me to keep open the possibility that we have the potential to manage energy in a manner consistent with some “mystical” claims.. i’m just not certain how many generations it will take to master such elusive disciplines.. But, we will create our own realities through our individual belief systems.. our individual realities will interact with those of others and a “quasi” reality will be agreed upon by the majority opinion.. Here is the fun, negotiating agreed upon realities that preserve our individual identities while maintaining a peaceful and prosperous society.. good luck!!
Be well..
