Tree pose or vrkasana is a standing balancing pose which stretches your entire body. This pose makes your legs, ankles and feet stronger besides making hips and knees more flexible.
When performing this pose, imagine your body stretching down through the supporting leg and up through your arms and shoulder through your bent leg. Sink your weight down through the supporting foot, which you can imagine as the root of the tree, to keep you steadfast.
You can also gaze at a fixed point and concentrate on your breath to maintain steadiness. You can place your hands or press your shoulder blades and buttocks against the wall to remain steady. Closing your eyes in this pose will be challenging both to remain steady as well as focus your mind.
