Janu Sirsasana (Head-to-Knee Pose): Meaning and Definition

What does Janu Sirsasana literally mean?

Janu Sirsasana is a compound formed from Janu, meaning “knee,” Sirsa, meaning “head,” and Asana, meaning “seat,” “sitting posture,” or, in modern yoga usage, “pose.” Read word by word, the name is “knee-head posture.” English-speaking yoga communities usually translate it more naturally as “Head-to-Knee Pose.”

The joined Devanagari form जानुशीर्षासन reflects the word as a single Sanskrit compound. Pedagogical sources sometimes write जानु शीर्षासन with a space so that students can see the component words more easily.

• Janu: knee
• Sirsa: head
• Asana: seat, posture, or yoga pose

How is Janu Sirsasana practiced in yoga?

In the commonly taught form, the practitioner sits with one leg extended and the other leg bent outward, placing the foot near the inner thigh of the extended leg. The torso turns toward the straight leg and folds forward along it. Hand placement varies according to mobility, teaching method, and the use of a strap or other support.

The English name describes the direction and general shape of the posture. Head-to-knee contact is not required for the pose to be recognizable or useful. Length through the spine, a steady breath, and an appropriate position for the bent knee are more relevant than forcing a deeper fold.

Because Janu Sirsasana is asymmetrical, it is generally practiced on both sides. Teachers may adapt the angle of the bent knee, support the knee or hips, or use a strap around the extended foot according to the student’s proportions and range of motion.

Why are there several English spellings?

The IAST transliteration is given as one compound: januśīrṣāsana. In common yoga writing, the diacritical marks are often removed and the word is divided into Janu Sirsasana.

Spellings such as Janu Shirshasana and Janu Shirsasana attempt to make the Sanskrit sounds more apparent to English readers. The letter combination “sh” may represent either of two Sanskrit sibilants in the word. Janu Sirsasana is a common simplified spelling, while the IAST form preserves the linguistic distinctions.

• Janu Sirsasana is a common simplified classroom spelling.
• Janu Shirshasana gives English readers a clearer visual cue for the sh sounds.
• Janusirsasana and Janushirshasana present the compound as one word.

How does the pose vary across yoga traditions?

The name Janu Sirsasana is used across several modern posture-based yoga traditions, although the exact form and method are not identical in every school. Some approaches emphasize spinal extension and supported forward movement. Others teach the posture within a counted Vinyasa sequence.

In Ashtanga Vinyasa Yoga, Janu Sirsasana A, B, and C are distinct postures in the Primary Series. The extended-leg forward fold remains a shared feature, while the bent foot and heel are positioned differently in each variation. Outside Ashtanga practice, the unqualified name Janu Sirsasana usually refers to a form similar to Janu Sirsasana A, with the sole of the bent leg’s foot placed near the inner thigh.

Janu Sirsasana is documented in T. Krishnamacharya’s Yoga Makaranda, written in the 1930s, and later became widely known through influential twentieth-century teaching traditions. Current evidence supports describing it as a well-established modern yoga posture. Claims that it is an ancient pose under this exact name require caution because premodern posture names and forms do not always correspond directly to modern ones.

What should yoga teachers communicate about the name?

Teachers can translate Janu Sirsasana as “Head-to-Knee Pose” while explaining that the name describes an orientation rather than a required endpoint. Students may experience the posture primarily through the back of the extended leg, the bent-leg hip, and the length of the back body.

The relationship between Janu Sirsasana and Paschimottanasana is especially useful in teaching. Both are seated forward bends, but Janu Sirsasana works asymmetrically with one knee bent. Dandasana commonly serves as the seated starting position from which the legs are arranged.
