Sitting bound half lotus revolved spinal twist

Also known as: Marichyasana D, Pose dedicated to the sage Marichi D.

Technique

Seated with the legs extended, bring the left leg into half lotus and the right foot back toward the hip with the knee up (see Sitting bound half lotus fold).
Keeping the weight forward in the left thigh and right foot, take the left elbow to the outside of the right leg.
Press the arm and leg into each other to bring you deeper into the twist and take the right hand to the floor behind you for support.
Then internally rotate the left upper arm to wrap it around the right shin.
Bring the right arm back around to bind with the left hand (fingertips or hand to wrist).
Continue sitting up tall as you gaze over the right shoulder and take 5 breaths.
Unfold and repeat on the other side.

Keep the spine tall as you twist. Support for this action comes from the deep core and psoas major muscles.
Avoid leaning backward or collapsing in the lower back as you twist.
It is common for the bent leg hip to lift off the ground in this posture. That is ok and actually quite normal.
This is an external rotation for the hip that is in half lotus, and an internal rotation for the bent leg with the foot down.
Tuck the half lotus foot securely into the hip crease before bending the other leg. Only bend that leg as far as is comfortable for the lotus ankle, knee and hip.
For tight shoulders, you could use a strap to make up the distance between the hands.

Logging: Work each side for the time indicated.

Risks

You’re trying to come forward enough that the foot and opposite thigh are the foundation of the posture, which means the lotus leg has to rotate externally even more. If it won’t go, DO NOT FORCE IT. This will put pressure on the knee rather than the hip, and potentially cause pain or harm.
This is also a strong bind for the shoulders. The back of the shoulder must be to the outside of the knee before wrapping around for the bind. Otherwise there will be pressure on the shoulder joint that may cause pain or injury.
