Peter Ralston began studying material arts at age nine in Singapore. He was a Sumo champion at his high school in Japan and a collegiate fencing and Judo champion while a Physiology/Anatomy major at the University of California at Berkeley. He founded the Cheng Hsin School in Oakland, where he teaches a range of courses on martial arts and ontology (the study of being).
"What Peter Ralston does remarkably well is to clarify what the
classics have been trying to tell us, and to offer concrete
direction on how to continue growing and become better in the
internal arts. You can't fix Cheng Hsin on the wall with a pin,
because, as you try, you realize that Cheng Hsin is the wall, and
the pin, and the action, and the intent."
