While I was caring for my mother, during a terminal illness in the hospital, someone gave me Lori Reed's book, "Palmistry."
I was fascinated and thought I'd look into learning more about it. Long story made short: that was 10 years ago and I'm still reading and studying.
I started out by reading Xerox copies of hospital staff's palms. That involved long, handwritten analysis, some times 5 or 10 pages. There really is a little world right in the palm of your hand.
I progressed to palm reading prior to giving a tarot reading.
I'm just as fascinated with a querent's odyssey through his/her palm as I am in awe of the person's life journey through the tarot. There is history in the palm and it's story is played out in the tarot.
If you develop your interest in Palmistry and are looking for the titles of resource material let me know.
Hope this helps you along your path.
