Zen Satsui is a way of being, harnessing seemingly contrasting energies. It is a calm aggression. Tranquil precision. Ruthless execution without resentment or animosity. 

The Zen Satsui symbol is simply a Z interconnected with an S 
This symbol mirrors the nature of the contrasting energies Zen Satsui balances
The two letters share a similar pattern, facing opposite sides
One drawn with straight rigid lines, the other soft and curved

The symbol can be repeated indefinitely into relative abstraction, following a meditative alternating flow 
between "straights" and "squiggles"
