This year we are discussing the Book of Martial Power (BOMP) on Saturdays.
Simplicity seems to be a mantra among the martial arts crowd. "KISS - Keep It Simple, Stupid," is one of the first lessons I learned. The basic idea is that when under extreme stress - like in a fight - we all become clumsy and stupid because of the adrenalin response.
This reasonably leads to the conclusion that you should formulate your martial system with the least number of moving parts and only a few of the most effective techniques - a sort of martial minimalism. That works great, and that's how I have learned from day #1.
But recently I've kept running across another idea - an alternative or corollary to the KISS principle. One that might be exemplified by a quote I've heard attributed to Einstein...
Everything should be made as simple as possible - but not simpler.
There's a core of martial stuff that is simple and effective, a kernel - but then there are dragons hiding in the interstices and magic in the shadows surrounding that kernel of simplicity.
