Control the line of scrimmage.
You hear that a lot in football. The line of scrimmage is the dividing line between the offense and the defense. It's the tug-of-war line.
It's the line you maintain when you practice yoga. You won't cross over into the offensive and you won't cross over into the defensive. The line is you - the middle road - the breaking point and the turning point - the place of stability. You try to stay steady on that line.
In football, when you control the line of scrimmage -- you control where the game is going.
In yoga, you sometimes lose this control and give in or push back. That's all right. Sometimes that's the only way to know where that line is. In you.
