Query: P.T. Barnum knew the market well

I am constantly amazed at how many self-appointed gurus are eager to proclaim the latest formulaic "secret" for indulging in every imaginable fantasy through magical thinking. Even more amazing is how many people buy into it. The formula is simple. Pander to the latest vogue in so-called "new age" thinking and add a sprinkling of traditional wisdom for faux credibility. The Tibetans have a term for it. "An admixture of gold dust and yak dung."The late Alan Watts made a humorous comparison between institutional Zen and institutional psychiatry in which he stated that, "Anyone who goes to a psychiatrist ought to have his head examined, and anyone who goes to a Zen master deserves 30 blows of the stick (kyosaku)." Perhaps we all get the guru we ask for."There isn't any special method. Attaching to thoughts, you get carried away in delusion and sidetracking yourself. So give it up. That's all there is to it" -Zen Master Bankei (1622-1693)
