Vīrabhadrāsana or warrior pose is an Āsana where the postural focus at the level of Annamaya or the structural aspect, involves the skill of holding opposite points of attention at the same time.
For example, if we consider the feet, the front foot focus is on the rooting of toes, whereas the focus on the rear foot is on the rooting of the heel.
Thus here we have an example of a Pratikriyā Bhāvana, or opposite action focus, where we need to hold our attention with a contrasting dynamic in two places simultaneously. In this example on both the front or rear foot at the same time, but with different points of attention.
