This year we are discussing the Book of Martial Power (BOMP)
Chapter 27 is a sort of a review chapter, but in it he does something remarkable! On the face of things, it is a note that henceforth in the book he will use the word "structure" as a shorthand for five recently-discussed principles...
But, more profoundly, and more importantly, Pearlman has managed to boil down much of the vague, pseudo-spiritual, mystical-sounding talk about 'structure' and 'ground-path' and 'root' and different 'energies' and such into a handful of easily-teachable, easily understood (though admittedly, not trivial to ingrain) principles.
Pearlman has gone a long way towards giving us the language we need to discuss the more vague, woo-woo, spooky parts of our arts.
