Kenpo Karate: The Art of Spontaneity - ISBN 0-9645386-0-1 By Sacha Williams By far one of my favorite books. It is any excellent continuation to Mr. Parker's works. Throughout the book references are make to all 5 of the Infinite Insight Volumes. Mr. William's ideas on Intervals are enlightening. His concept of technique grouping to learn spontaneity is very helpful and his photographic illustrations are numerous and excellent. Need I say more.
