Stand with the bases of your big toes touching, heels slightly apart (so that your second toes are parallel). Lift and spread your toes and the balls of your feet, then lay them softly down on the floor. Rock back and forth and side to side. Gradually reduce this swaying to a standstill, with your weight balanced evenly on the feet.
Step 2:
Firm your thigh muscles and lift the knee caps, without hardening your lower belly. Lift the inner ankles to strengthen the inner arches, then imagine a line of energy all the way up along your inner thighs to your groins, and from there through the core of your torso, neck, and head, and out through the crown of your head. Turn the upper thighs slightly inward. Lengthen your tailbone toward the floor and lift the pubis toward the navel.
Step 3:
Press your shoulder blades into your back, then widen them across and release them down your back. Without pushing your lower front ribs forward, lift the top of your sternum straight toward the ceiling. Widen your collarbones. Hang your arms beside the torso.
Step 4:
Balance the crown of your head directly over the center of your pelvis, with the underside of your chin parallel to the floor, throat soft, and the tongue wide and flat on the floor of your mouth. Soften your eyes.
Step 5:
Tadasana is usually the starting position for all the standing poses. But it's useful to practice Tadasana as a pose in itself. Stay in the pose for 30 seconds to 1 minute, breathing easily.
Beginner's Tip:
If you tilt onto the twisting-side buttock (which compresses the lower back), raise it up on a thickly folded blanket. Consciously sink both sitting bones toward the floor.
Modifications and props:
For an easier variation of this pose, sit sideways on a chair with the chair back to your right. Bring your knees together and your heels directly below your knees. Exhale and twist toward the chair back. Hold onto the sides of the chair back and lift your elbows up and out to the sides, as if you were pulling the chair back apart. Use the arms to help widen the upper back and move the twist into the space between the shoulder blades.
Deepen the pose:
You can increase the challenge in this pose by slightly varying the position of the arms and hands. First, exhale and swing your right arm around behind your back as you twist to the right. If you can, grip the left arm just at the elbow with the right hand; if you can't, hold a strap looped around the left elbow. Then turn your left arm outward (so the palm faces away from the knees) and slip the hand under the right knee, palm on the floor.
Partnering:
A partner can help you learn to ground the opposite-side buttock. If you are twisting to the right, have your partner stand to your left side and place his/her left foot on the very top of your left thigh, with the inner edge of the foot in the groin. Apply gentle pressure at first, then increase the pressure as seems appropriate. Exhale into your twist but keep the top left thigh releasing away from your partner's foot.
