Marīchyāsana C (Sage Marīci C) is the first twist in the Marīchyāsana series and introduces spinal rotation into the seated sequence. Unlike the forward folds of A and B, the C variation features a deep twist toward the bent-knee side with a binding arm. It has a reduced vinyāsa count compared to the forward-fold variations, reflecting the different energetic quality of twisting versus folding.

Named after the sage Marīci (ray of light), the same as all Marīchyāsana variations. The 'C' variation introduces the twist element. In the traditional Ashtanga system, the naming convention is: A (fold), B (fold + lotus), C (twist), D (twist + lotus). This pattern reveals the systematic logic underlying the sequence design attributed to Krishnamacharya and Pattabhi Jois.

Marīchyāsana C has an 18-vinyāsa count — four fewer than the forward-fold variations (A and B). Right side: vinyāsa 7 (Saptaḥ) — jump through, bend the right knee with the right foot flat on the floor, twist to the right, wrap the left arm outside the right knee, bind, held for five breaths. Transition vinyāsas 8–11. Left side: vinyāsa 12 (Dvādaśa) — bend the left knee with the left foot flat on the floor, twist to the left, wrap the right arm outside the left knee, bind, held for five breaths. Exit vinyāsas 13–18. The shorter count reflects the absence of the intermediate 'head up' position between fold and exit.

From Adho Mukha Śvānāsana, inhale jump through. Bend the right knee and place the right foot flat on the floor, heel near the right sit bone, as in Marīchyāsana A. The left leg extends straight. Twist to the right, bringing the left arm to the outside of the right knee. Wrap the left arm around the right shin from outside to inside, and reach the right arm behind the back to clasp the left wrist. Deepen the twist on each exhale. Hold five breaths.

In the full expression, the torso rotates deeply toward the bent-knee side. The opposite arm crosses the body and wraps around the outside of the bent shin, binding behind the back with the same-side arm. The twist originates from the base of the spine and spirals upward through the thoracic spine. The head turns to look over the back shoulder. The extended leg remains straight and active. The chest lifts and opens with each inhale, and the twist deepens with each exhale.

Inhale maintain the twist with a lifted chest. Exhale release the bind and unwind the twist. Straighten the bent leg, cross ankles, inhale lift, exhale jump back. Complete the vinyāsa for the left side.

Pārśva dṛṣṭi (far to the side/over the back shoulder). The gaze turns in the direction of the twist, looking over the shoulder of the bent-knee side. This dṛṣṭi completes the rotational action through the cervical spine.

Mūla bandha anchors the pelvis, providing a stable base from which the twist can ascend. Uḍḍīyāna bandha is essential for creating length in the spine before rotation — the axiom 'lengthen before you twist' depends on the upward drawing quality of uḍḍīyāna. Without bandha engagement, the twist tends to compress rather than lengthen the spine.

The twist initiates from the lower spine and progresses upward. The arm crosses the body so that the outer upper arm or armpit contacts the outer knee — this is the lever for the twist. The shoulders remain level (the twisting shoulder does not drop). The spine stays vertical, not leaning. The bent-knee foot is firmly grounded. The extended leg is active with the kneecap lifted and foot flexed.

Initiating the twist from the shoulders or neck rather than from the base of the spine. Leaning the torso away from the vertical to get the arm past the knee. Collapsing the chest and rounding the spine, which compresses the vertebral discs. Allowing the bent-knee foot to lift off the floor. Holding the breath during the twist, which prevents deepening.

The twist engages the internal and external obliques asymmetrically, the deep spinal rotators (multifidus, rotatores), and the intercostal muscles. The binding action requires significant shoulder mobility — internal rotation of the wrapping arm and extension of the other. The thoracolumbar fascia is mobilized by the rotation. The psoas and quadratus lumborum are stretched on the side opposite the twist.

Twists are considered deeply therapeutic in Yoga Cikitsā. Marīchyāsana C is said to wring out the abdominal organs, improving circulation to the liver, spleen, and kidneys. The twist stimulates peristalsis and aids digestion and elimination. It is therapeutic for mild back pain by mobilizing the thoracic spine and releasing tension in the paraspinal muscles. The rotation also helps maintain intervertebral disc health.

If the bind is not accessible, hook the elbow outside the knee and press the palms together in a prayer position (añjali mudrā) at the chest. A strap behind the back can bridge the hand gap. If the extended leg's hip lifts during the twist, focus on grounding both sit bones before deepening the rotation. The teacher can assist by gently guiding the twist deeper using the student's shoulders as leverage, always coordinating with the exhale.

Marīchyāsana A establishes the bent-knee and binding foundation. The standing twisting poses (Parivṛtta Trikoṇāsana, Parivṛtta Pārśvakoṇāsana) develop spinal rotation. Bharadvājāsana (not in Primary but a common warm-up) is an accessible seated twist that prepares the pattern.

The vinyāsa between sides neutralizes the spine. Marīchyāsana D follows immediately, adding the lotus to the twist. After the complete Marīchyāsana series, Nāvāsana provides a symmetrical, extension-based counterpose that resets the spine from both the twisting and folding of the entire series.

Twisting postures are often described as the 'cleansing' component of the practice. Just as wringing a cloth expels water, twisting the body is said to squeeze out toxins and stagnation. In the broader philosophical context, the twist represents the ability to look behind oneself — to examine the past and one's conditioning (saṃskāras) with clarity. Marīci's quality of illumination supports this: the twist brings light to what is hidden.
