There are two reasons. First, a very large number of people are sick these days and spiritual healing might help some of them. The second, as I pointed out in a blog post last month, is that there's good reason to think that we're close to the edge of a very traumatic period of transition and disintegration here in the US and in the rest of the industrial West, so the sooner I get this stuff into people's hands, the more likely the tradition is to survive.
