Matsyendrasana

The Pradipika describes placing the foot at the root of the thigh, drawing the knee close and turning the body — a posture credited to Matsyendranath, one of the founding figures of the hatha tradition. The text claims it kindles the digestive fire and awakens the serpent power, its language for the energy the practices are meant to rouse. Twists occupy a specific place in classical sequencing: they follow folds and backbends and precede the seated breath practices, returning the spine to neutral and, in the tradition's terms, wringing out what the earlier postures loosened. Most practitioners work with the half version, ardha matsyendrasana.

1. Sit on a folded blanket with the legs extended.
2. Bend the right knee and place the right foot outside the left thigh, sole flat.
3. Bend the left leg and bring the left heel beside the right hip, or leave the left leg straight.
4. Inhale and lengthen the spine upward.
5. Exhale and turn to the right, left elbow outside the right knee, right hand on the floor behind.
6. Keep both sitting bones grounded and the neck turning last.
7. Hold five slow breaths, lengthening on each inhale and turning slightly on each exhale. Repeat on the other side.

Rotation is distributed unevenly through the spine: the thoracic region rotates readily, the lumbar region very little. Pulling hard with the arm to twist further mostly loads the lumbar segments and the sacroiliac joints, which is the usual source of post-twist discomfort. The useful instruction is to lengthen upward first, then rotate from the mid-back with the breath, using the arm only as a light lever. Sitting on a folded blanket keeps the pelvis level and prevents the lower back from taking the rotation. Twisting positions do compress and release the abdominal contents, and gentle abdominal movement has a mild supportive effect on gut motility — a modest version of the text's claim.
