Stand in Mountain Pose or Tadasana (standing, arms at your sides, feet together) and begin to shift all of your weight into the ball of your left foot, rocking forward slightly to produce even  weight distribution through your entire standing foot and leg. Lift your right leg until your thigh is 45° and perpendicular to the floor, flex your foot. Grasp your right knee lightly and swivel bent leg to the right, opening your thighs. Place your right foot on your upper thigh/groin (level II-II) or to your knee/shin (Level 0-I).  Keeping your knee as far to the right as possible, pressing into your inner thigh with your foot (level II-III,) building restriction or push/pull. Once you are firmly rooted in your standing leg, choose your favorite arm variation (see below.) 

Variations

Level I: Place lifted foot just above your knee cap, keep your hands in prayer position at your heart center and find a drishti on the floor in front of you.

Level II: Raise your arms straight up and gaze at your drishti* in the sky.

Level III: Raise your arms to the sky, clasp hands pointing index fingers up and gaze at your drishti* in the sky or close your eyes. Another advanced variation is reversed prayer behind your back (pictured here.)

 *A Drishti is a focal point usually 2-3 feet in front of you if gazing down or any place skyward that is comfortable for your neck.
