Part Three in a Series
Dear friend,
If you have ever finished a practice and felt something moving inside you that had no name, you have already met the subtle body.
A warmth at the base of your spine. A softening behind the heart. A quiet humming along the breath. These are not imagined. They are the ancient inner architecture the sages mapped long before modern language could describe it.
And the Hatha Yoga Pradipika is one of the great maps.
In the last post, we explored the body and the breath as Svatmarama taught them. Now we step gently into the territory the practice was truly designed to open. The energy body. The river beneath the river.
The Nadis: Rivers of Light
The Hatha Yoga Pradipika describes thousands of nadis, subtle channels through which prana, our life force, flows.
Three are essential.
Ida, the lunar channel, runs along the left side of the spine. She is cooling, receptive, the energy of the moon and the inward gaze.
Pingala, the solar channel, runs along the right. He is warming, active, the energy of the sun and outward expression.
Sushumna is the central channel, the still river that runs through the core of the spine. When ida and pingala are balanced, sushumna awakens. And when sushumna awakens, something extraordinary becomes possible.
This is why we practice. Not to twist into shapes, but to balance these inner currents so that the deeper river can begin to flow.
Kundalini: The Sleeping Shakti
At the base of the spine, the Hatha Yoga Pradipika tells us, rests a coiled and luminous energy called kundalini shakti. She is often described as a sleeping serpent, the dormant feminine power of the universe held quietly within each of us.
She is not something to chase or force. She is something to invite. As our practice deepens, as the nadis clear and the breath steadies, she begins to stir. She rises through sushumna, awakening each chakra as she ascends, until she meets her beloved at the crown, and the practitioner is bathed in the light of pure awareness.
This is the heart of hatha yoga. Everything else is preparation.
Mudras and Bandhas: The Gentle Keys
Svatmarama devotes an entire chapter to mudras (energetic seals) and bandhas (subtle locks). These are not dramatic techniques. They are quiet, refined practices that direct prana inward and upward, supporting kundalini as she rises.
You may already know some of them: Mula bandha, the root lock. Jalandhara bandha, the throat lock. Uddiyana bandha, the upward flying lock. They are the keys that gently open the inner doors.
What Comes Next
In the posts to come, we will walk this rising path together, chakra by chakra.
From the grounded earth of muladhara to the flowing waters of svadhisthana, all the way up to the radiant crown. Each one is a doorway. Each one a homecoming.
This is the inner pilgrimage that hatha yoga was always meant to be.
If you feel the river stirring within you, come practice with me. My live Zoom classes hold this energetic awareness in every session. You are always welcome.
With love,
Prema
