Iyengar Yoga is known for its clarity and precision, but that outer structure is only the beginning. Prashant Iyengar identified three interconnected dynamics that operate in every pose: the physical, the energetic, and the mental. By tuning into these layers, we begin to understand that the real power of asana lies beneath the surface.
In Yoga Rahasya, Prashant Iyengar outlined three ways to study and understand an asana—not as separate steps, but as simultaneous and interwoven processes.
Each of these dynamics offers a different lens for self-study, and together they reveal how the practice of asana can reach beyond the physical body.
Physiodynamics: Building the Framework
This is where the work begins: establishing the shape through the alignment of bones, joints, and muscles. In Trikonasana, this might involve rotating the thigh outward, extending the spine laterally, and stabilizing the back leg.
But Prashant emphasizes that it's not enough to simply mimic a form. The outer structure should be purposeful—set up to support the internal work that follows. As he puts it, when there is no real involvement or intention, we’re just holding a position.
Biodynamics: Observing the Flow
With the physical structure in place, we can begin to notice the inner activity of the pose: how the breath moves, how energy shifts, and where there may be constriction or release.
Prashant described this as “giving freedom” to the breath and energy—not forcing anything, but clearing a path through correct effort and attention. In Trikonasana, for example, you might notice how one side of the chest expands more than the other—or how the lift of the spine supports a smoother inhalation.
This layer is subtle. It requires patience and quiet attention. But it’s often here that the pose begins to feel alive.
Psychodynamics: The Mind Inside the Pose
The third layer is often the most difficult to name—and the easiest to overlook.
How is the mind affected by the pose? Does it quiet down, or does it become more active? Are you concentrated, or scattered? Involved, or going through the motions?
Prashant pointed out that our mental state is not separate from the pose. It influences how we enter, sustain, and exit the asana. A restless or disconnected mind will always shape the experience, whether we’re aware of it or not.
Through continued observation, we learn how to engage the will—not as force, but as attention that’s steady and sincere.
Practice Suggestions
Choose one pose—Trikonasana works well, but it could be any familiar standing or seated pose—and explore it through these three lenses:
First, physiodynamics: Is the pose structurally sound? Are the joints well-placed and the limbs alert without strain?
Then, biodynamics: What’s happening with your breath? Is there evenness or effort? Where do you feel energy moving—or getting caught?
Finally, psychodynamics: What’s your state of mind while holding the pose? Are you attentive or distracted? Does the pose help create clarity, or confusion?
And one last question:
What lingers after the pose?
Steadiness? Agitation? A shift in your perspective?
Why This Matters
Asanas aren’t just shapes to memorize. They’re tools for transformation—but only when we know what to look for. Geeta Iyengar’s insights remind us that asana is not something we do to the body. It’s a method of study—of the breath, the mind, and the self.
This approach doesn’t require new poses. It requires a new way of seeing.
