the one thing i thought was interesting about your picture is that you did it backwards.. kind of a play on pixels, if you catch my data-stream..
the meaning behind Inner Calm Outer Fury is a few things.
The fury could be considered as our fighting, which is furiously vicious when we choose it to be, and the calm can then be describing our true personality on the inside: amicable, respectful, good sportsmen, polite, honest and honourable.
Or it could be considered as a way to define the distinction between relax style and hold style.
Just make your own interpretations and go from there.
