The ability to heal is given to humankind - but for most people
it lies dormant. And that's a good thing, because when you use
it, qi is emitted, and as long as we don't have effective
methods to strengthen our qi, we will tire ourselves out by
emitting it, ultimately shortening our own life expectancy.
This ability goes back to human predispositions, which are
often better preserved in original ways of life than in modern
environments.
