Well, it's manipulating your ki, which is something that everything that's living has. Once you know how to do it, it's just doing that to do whatever it is that you need to do, like making your attacks stronger or flying or shooting blasts of it.
Unfortunately, it's not really something that's super documented anywhere, so anyone who would be learning how to do it would have to learn from someone else who already knows how. Which is why not that many people know how to do it.
... Well, that and the fact that it's still hard to actually do.
And yeah, I'd hope the same if I saved someone, but some people can be a little weird about things like that.
