The target.

Visualize all world events presented to the mind on a graph with cross-hairs.

On the horizontal axis, positive is attractive causing rAga, negative is repulsive causing dveSha.

On the vertical axis, positive is what is perceived as good or puNya or what is perceived as dharma, and on the negative is what is perceived as bad, or apuNya or adharma. 

The mind should ever rest in the center, the cross hairs, the target, Om.
