It is a natural inclination of human existence for us to either rush into the future or get stuck in the past. We can observe this experience in a non-threatening way when we are doing our yoga poses.
Virabhadrasana II is a foundational standing pose that represents one of the many stances of the fierce warrior Virabhadra, who according to Hindu mythology ia a super being who was created by the wrath of Rudra/Shiva. According to legend, Virabhadra had a 1,000 arms and a 1,000 weapons so the three Virabhadrasana postures that we commonly practice may in theory just be the tip of the iceberg in terms of how Virabhadra may be expressed through yoga asana.
Virabhadrasana II is a foundational standing pose because it trains us to have both strength and stability in the legs and hips while at the same time cultivating length and space in the groins. According to B.K.S. Iyengar, the chest naturally drops when we bend our front leg in this pose which is contrary to the vitality we want to express in the chest. I trust Mr. Iyengar, but you don't have to, try it for yourself and see! Not only does the chest drop, but as soon as we begin to bend the front leg, our attention moves forward chasing a future state and the back leg and arm are left behind. In fact, you can see in my photo, that this begins to happen as soon as we turn the back foot in: the waist begins to concave on that side and the chest drops.
To counteract this, as you turn your left foot in, keep your gaze to the left, grounding the outer left heel, filling the flesh of your left side waist and keeping your chest lifted. With your gaze still to the left and maintaining the above actions in the left side, bend your right knee to 90 degrees.
Now, spread your awareness from the left side to the right side without losing awareness on the left. If you get this right, you may experience a glimpse of the present moment between the past on the back leg and the future in the front leg. Keeping your awareness on the left side, slowly turn your head to the right. Stay in the present moment by continuing to adjust and reflect in the pose. Observe, when you mind begins to stray. Where is it straying? Again and again, bring yourself back to present moment awareness using the left and right sides of your body for reference.
YS.II.47 prayatna saithilya ananta samapattibhyam
Perfection in an asana is achieved when the effort to perform it becomes effortless and infinite being within is reached.
"When the sadhaka has reached that state of balance, attention, extension, diffusion and relaxation take place simultaneously in body and intelligence and they merge into the seat of the soul." -Light on the Yoga Sutras of Patanjali, B.K.S. Iyengar
