Too many questions.
I have tested many of the assumptions of Classical Palmistry over thirty years of practice, and do read by the "rules." The ones that work. I've tried to separate the good techniques from superstition. So I don't, for example, predict how long someone will live based on the length of the Venusian line. I do use the Greco-Roman archetypes and Jungian aspects, as well as my own Buddhist practice, during a session. Which can get very interesting. I've written three large volumes on my researches which have been well-received. Unfortunately, Llewellyn targets an audience with an adolescent literacy level, so I was unable to write on the intellectual depth I desired .
Dr. Gary Schwartz at one time offered to do a study with me testing under controlled conditions some of my conclusions, but I don't think anything came of it. He has been too involved in his medium research. I've also done a very fascinating study on my own involving over forty sets of twins to test the theory that the dominant hand changes over time to reflect changes in personality. Guess what? It does.
The people who hold someone's hand and draw upon their own clairvoyance are not really palm readers .

They're clairvoyants. I wish they wouldn't call themselves palm readers. Oh Well.
Discussing Criss Angel on this forum lowers the tone of the event; like bringing in a birthday party clown to a formal dinner party, don't you think?
