Huh, so it's a known thing, although the site doesn't provide very specific
information. My searches have thus far yielded meditation exercises, and the
exact mechanism by which this would be possible isn't yet clearly explained.
At least, not for things like eye or hair color. Being that the rest of the body
is controlled via the brain, I can understand how those functions can be
controlled.

They see their body as a machine that that is what makes it simpler for them to disassociate themselves from their ego.
I have witnessed a yogi in a state of ecstasy perhaps only 6 months ago. I
see him every now and then around the beach, have heard him discuss his
practice to others on occasion, and at other times have seen him meditate.
He is old from what I make of him. Not that I wish to get off topic or
anything, but yes, I understand that yogis tend to be capable of interesting
mental abilities, not unlike those of the monks and some indigenous shamans
of the world.

Gene therapy may well do the job, but that technology is years away from reality.
And what of the kind of mental stress that causes a person to, say, grey
early (hair)? There are things the brain can do that effect the body and
indirectly effect those things that it would be otherwise unable to, is that
correct? I understand though that it should not be possible to change
something like eye color. There may yet be a way, in any case, and I'm only
trying to consider possibilities.
