This article is part of Yoga Journal’s ongoing Archives series, a curated collection of seminal works originally published in our print issues beginning in 1975. The following insights regarding Pigeon Pose (Eka Pada Rajakapotasana) were first featured in the July-August 1987 edition of Yoga Journal.
The Philosophy of Perception: Why "All Knowledge Comes from the Skin"
"All knowledge comes from the skin!" This proclamation, delivered by B.K.S. Iyengar nearly four decades ago at his institute in Pune, serves as a cornerstone for understanding the intersection of physiology and spiritual practice. For the practitioner, the statement can feel cryptic, yet it finds profound resonance in the study of human development and the intricate mechanics of the nervous system.
In his seminal work, Touching: The Human Significance of the Skin, Ashley Montagu posits that body awareness is not an abstract mental construct, but a physical reality birthed through stimulation. "Body awareness," Montagu writes, "is produced through stimulation of the body, chiefly through the skin, and this commences at birth, if not before."
The physiological journey begins in the womb. The hours of labor a mother endures are, in effect, a sensory primer for the infant. The rhythmic contraction of the uterus acts as a massive tactile stimulation of the fetal skin, which in turn triggers the autonomic nervous system. This process sets the stage for the independent functioning of the respiratory, digestive, and eliminative systems. To the yogi, this is not merely biological; it is the physical manifestation of prana (life force) meeting the material world.
The Fourth Chakra: Where Breath Meets Touch
Ancient yogic traditions recognized this intimate link between the skin and the breath through the symbolism of the Anahata (Heart) chakra. Located in the thoracic region, the fourth chakra is governed by the element of air and the sense of touch.
Unlike sight, which often acts as a source of division—fueled by perceptions of dress, appearance, and social standing—touch is a unifying force. It bypasses intellectual judgment and communicates at the level of our shared humanity. Because the skin is the primary organ of touch, it serves as the physical anchor for the heart chakra’s qualities: compassion, love, and healing. By focusing our awareness on the skin, we are not just performing a stretch; we are engaging in an act of profound self-empathy.
B.K.S. Iyengar’s Experimental Approach to Healing
B.K.S. Iyengar’s own evolution as a teacher was defined by his radical insistence on treating the skin as an "organ of perception" rather than a mere anatomical covering. Reflecting on his early years, Iyengar recalled the necessity of this shift:
"When I noticed the water gradually changing [during cleansing], my attention went onto the skin. I asked myself what is the skin’s duty while performing asanas? Is it just an anatomical cover of the body, or is it an organ of perception? … When I started moving the skin, the smell started disappearing, and I realized why ancient people said the skin is an organ of perception."
This discovery led to the core of the Iyengar method: the quality of the skin reflects the quality of the internal organs. If the skin of the rib cage is rigid or insensitive, the intercostal muscles contract, effectively "caging" the lungs and restricting the breath.
Practical Application: The Rib Cage Experiment
To experience the correlation between skin awareness and respiratory expansion, one can perform a two-part experiment in Savasana (Corpse Pose).
- Phase One: Lie still and focus your mental attention solely on the internal lungs. Observe the movement in the abdomen and the rib cage. You will likely find the breath to be shallow or concentrated solely in the sternum, with little movement in the side ribs.
- Phase Two: Shift your awareness to the skin of the rib cage. Visualize the skin becoming porous and receptive. Notice how this shift in focus naturally invites the rib cage to rise like the swell of the sea. Without conscious effort to "take a deep breath," the lungs expand to fill the newly created space.
Implications for Advanced Asana: The Pigeon Pose Sequence
This philosophy of skin awareness is vital when approaching advanced backbends, specifically Eka Pada Rajakapotasana (One-Legged King Pigeon Pose). The name itself implies a chest that is lifted and puffed like a bird, signaling the pose’s deep connection to the heart chakra.
Building Blocks of Practice
Eka Pada Rajakapotasana is not for the novice. It requires a foundational mastery of Salabhasana (Locust), Dhanurasana (Bow), and Urdhva Mukha Svanasana (Upward-Facing Dog).
Variation I: Pelvic Alignment and Thigh Release
Tight quadriceps are the primary obstacle to a healthy backbend. When the front thigh is rigid, the pelvis cannot rotate properly, leading to lumbar compression.
- The Setup: From a kneeling position, slide the right knee toward the right hand. Ensure the back leg is extended straight, with the median line of the thigh flush with the floor.
- The Support: Use a bolster or folded blanket under the front hip to ensure the pelvis remains level.
- The Action: Roll the shoulders back, extend the arms as in Urdhva Mukha Svanasana, and lift the skin of the lower abdomen toward the navel.
Variation II: The Abdominal Release
Using a rolled blanket as a "rolling pin" across the lower abdomen (just above the pubic bone) can help release the psoas muscles. By pressing into the roll, you create a fulcrum that encourages the lower abdominal muscles to lift, protecting the lower back while facilitating a deeper spinal extension.
Variation III: Integrating the Chest
Once the pelvis is stable, students can work on the upper chest. By bringing the hands into namaste behind the back, the practitioner forces the rib cage to lift. For those with more flexibility, the head may drop back, but only after the chest has been fully opened.
Variation IV: The Final Expression (The Strap Method)
For the full expression, a strap is essential to maintain the structural integrity of the shoulders and rib cage.
- The Technique: Place the strap around the back ankle. As you walk the hands along the strap toward the foot, focus on lengthening the skin of the outer armpits.
- The Goal: The goal is not merely to touch the foot, but to move the back shin away from the chest while simultaneously lifting the rib cage. This creates the "rainbow arch" characteristic of the pose.
The Paradox of Effortless Breath
Many students question why B.K.S. Iyengar avoided traditional, direct "breath work" during asana practice. The answer lies in the subtlety of the nervous system: direct manipulation of the breath often leads to an artificial, labored rhythm.
By working indirectly—through the movement and awareness of the skin—we trigger the body’s innate, self-regulating mechanisms. We move from a state of forcing to a state of being. Much like the mother’s touch that matures the newborn’s respiratory system, our own awareness acts as a "healing touch" of the mind.
In Eka Pada Rajakapotasana, when the breath begins to flutter with the intensity of a bird’s heart, the practitioner should not attempt to hold or control the air. Instead, release the skin of the front chest, create space between the ribs, and allow the body to reach its own natural, rhythmic homeostasis.
Conclusion
The legacy of B.K.S. Iyengar’s 1987 teaching remains as relevant today as it was during that session in Pune. By shifting our perspective from the internal "work" of the organs to the external "wisdom" of the skin, we unlock a deeper dimension of yoga. The skin is the boundary between the self and the world, and by softening that boundary, we allow the heart chakra to open, the breath to deepen, and the body to find its ultimate, unforced expression. Whether in the simplest Savasana or the most challenging King Pigeon Pose, the invitation remains the same: feel the skin, trust the response, and let the breath follow the wisdom of the touch.
