The point of this thread, i think, is to determine whether rainbow body (and by extension, any extraordinary phenomena) can be scientifically validated, and that means repeated in blind case studies and so forth.
It is very easy to fake miracles. So, even internet videos (or perhaps especially internet videos) need careful scruitiny.
But, when the extraordinary becomes common, and can be repeated, then there is some sense of validation. And what I am specifically thinking about is the ability to smash through bricks and things which is a commonplace demonstration in the martial arts. We can understand the physics behind being able to push the edge of your hand through a cinder block, because the speed of force counters the fact that cinder blocks are hard and out hands are fleshy and easily broken. These days, people glide through the air in suits that mimic the body of a flying squirrel. What is unbelievable quickly becomes believable when an explanation is given, which is compatible with our understanding of how things actually work. The problem is that before adequate research can be done, the miraculous events are consumed in a whirlwind of fakes and hucksters, and 99% of investigations turn out to be hearsay, anecdotal reports or just lies. We never find out how some of these amazing feats actually work, and thus, whether they are real or not.
As long as one is not basing their course of action, their Dharma practice ... or medical needs, for example, on unsubstantiated claims, then little harm is done. The dangers arise when people find causes for either ailments or for their cures, which do not actually exist, or practice dharma with the goal of someday being able to float in the air.
One thing I have always found amusing is that so very often 'spiritual' people condemn "western scientific thinking" as being close-minded, but the moment a research facility publishes the findings of a scientific study that supports something like the benefits of meditation on the brain, or whatever, those very same people wave that study around as validation.
I have a friend who is an artist and he says a painter only creates half of the picture
...the viewer paints the other half.
I think there is a lot of truth to this.
Profile Picture: "The Foaming Monk"
The Chinese characters are Fo (buddha) and Ming (bright). The image is of a student of Buddhism, who, imagining himself to be a monk, and not understanding the true meaning of the words takes the sound of the words literally. Likewise, People on web forums sometime seem to be foaming at the mouth. Original painting by P.Volker /used by permission.
