The importance of consistency for nervous system regulation

This essay will discuss the power of abhyāsa in regulating your nervous system. In the Yoga Sutras of Patanjali, we are reminded that transformation is rarely dramatic. More often, it is subtle, steady, and almost invisible while it is happening. Transformation often depends upon consistency.

Patañjali writes:

Practice becomes firmly grounded when done for a long time, without interruption, and with sincere devotion.
– Yoga Sutra I.14

This teaching on abhyāsa, steady practice, is deceptively simple yet contains one of the most profound truths about growth.

Real transformation is not built in bursts of inspiration, it is built through commitment.

Commitment is showing up when you feel motivated, and also when you do not.

It is the decision to return.

Again…
and again…
and again.

A Story About Showing Up
The Power of Abhyāsa: Regulating Your Nervous System

Years ago, there was a student who came to practice not because she felt inspired but because she was unraveling.

She didn’t arrive radiant or strong. She arrived tired, tight and guarded.

Her breath was shallow, her shoulders lived somewhere near her ears, and her jaw carried a constant tension she didn’t even recognize anymore.

She told me once, almost apologetically, “I don’t think I’m doing this right.”

But she kept coming.

Not every day, not perfectly. But consistently enough that something began to shift.

At first, it was barely noticeable.

She lingered in sivasana a little longer.
Movements softened.
Exhales stretched without effort.
Months passed.

One day after class, she paused and said, “Something is different. I don’t react the same way anymore.”

Not in a dramatic life-altering revelation but in an average moment earlier that day when she realized she had been interrupted. Instead of tightening, defending or collapsing, she had simply breathed and responded instead of reacting.

That was it.
No fireworks or breakthrough moment.
Just a different relationship to stress, frustration and the simple, inevitable challenges of everyday life.

This is how practice works.

Not in grand gestures, but in subtle rewiring. This is an example of consistency in a yoga practice supporting nervous system regulation.

Tapas: The Inner Fire

In yogic philosophy, tapas is often translated as discipline, but its deeper meaning is heat, the inner fire that purifies and refines us.

Tapas is what carries you to your mat on the days when inspiration and motivation are absent. It is what keeps you in the posture when your mind wants to escape. Tapas is what anchors you to stay present with sensation instead of bypassing it. Over time, this steady inner heat becomes tejas: a radiant clarity and unmistakable presence.

You can feel it in certain people. Not because they are loud or impressive, but because something in them has been shaped by devotion. There is a steadiness, a groundedness, an unassuming confidence that cannot be performed.

This is the alchemy of practice. Perfection is not required.
Consistency is. This is abhyāsa.

The writer Margaret Atwood once said:

“A word after a word after a word is power.”

The same could be said of practice.

A breath after a breath after a breath is abhyāsa.

What Science Tells Us: The Nervous System and Repetition

While ancient yogic texts spoke of transformation through repetition, modern science is now catching up to explain why this works.

According to Polyvagal Theory, our nervous system is constantly scanning for cues of safety or threat.

When the body perceives threat, it moves into survival responses:

• Fight
• Flight
• Freeze

For many people, especially those who have experienced chronic stress or trauma, the nervous system can become conditioned to stay in these states. This is where consistent practice becomes powerful.

Each time you:

• Slow your breath
• Feel your body
• Move with awareness
• Pause and notice

You are sending a signal to the nervous system:

You are safe.
Not once, but repeatedly. Over time, these repeated signals begin to repattern the system.

Neural pathways shift.
The vagus nerve strengthens its capacity for regulation.
Your body learns that it does not need to stay on high alert.

This is called neuroplasticity, the brain’s ability to change through experience.

But here is the key:

Neuroplastic change does not happen through intensity. It happens through consistency. Small, repeated experiences of safety. Again and again. This is the power of abhyāsa. Consistency in yoga practice for nervous system regulation

Subtle Shifts in the Body

One of the most remarkable aspects of steady practice is how the body begins to change. At first, the changes are obvious:

Strength.
Flexibility.
Balance.

But then something more subtle unfolds.

The breath deepens without forcing it.
Your shoulders soften in places that once held tension.
The jaw unclenches.
Your spine begins to organize itself with less effort.

And beneath all of this, the nervous system begins to regulate.

Old patterns of bracing soften.
Reactivity gives way to responsiveness.
The body remembers how to settle.

These changes are not dramatic. They are incremental and based upon self-awareness.

Like water slowly smoothing the edges of stone.

Planting Seeds

Abhyāsa is a lot like gardening.

Plant seeds.
Water the soil.
Care for the environment.

And then… you wait. Patiently. Calm. With trust that something is happening beneath the surface.

Many of the most meaningful shifts in yoga happen this way.

You practice for weeks or months wondering if anything is changing. And then one day you notice:

Your breath is steadier, reactions are softer, and your mind is less entangled in unnecessary worry.

Even your habits begin to change. You may find yourself craving nourishing food instead of stimulation. Choosing quiet over noise. Seeking connection over distraction. The seeds have been growing all along. Consistency regulates the nervous system.

Patience Without Expectation

In the Bhagavad Gita, Krishna offers a teaching that beautifully complements this path:

“You have a right to your actions, but never to the fruits of your actions.”

Practice wholeheartedly. But release the need to control the outcome. When we grip too tightly to results, we create tension. When we practice with devotion and let go of expectation, we create space. And in that space, transformation unfolds naturally.

The River Is Always Changing

There is an old insight often attributed to Heraclitus:

“You cannot step into the same river twice.”

The water is always moving. The current is always shifting. And so are we. Each time you practice, you meet a new version of yourself. Some days you feel open, some days you feel resistant, some days you feel nothing at all. All of it belongs. The only constant is change.

Returning Again and Again

This is the power of abhyāsa. Not in any single moment of practice but in the accumulation of moments.

Returning to the breath, to awareness, and to presence.
Again and again.

Little by little, the nervous system settles. Perception sharpens. Wisdom begins to arise from within. And slowly, almost imperceptibly, the practice that once felt like effort begins to feel like home.

If you feel drawn to deepen this relationship with practice, our 200-hour and 300-hour yoga teacher training immersions are designed to support exactly this kind of steady transformation through daily yoga, philosophical study, nourishing plant-based meals, and the companionship of a thoughtful global community. We offer consistency to regulate the nervous system so that it is possible to keep showing up.

Because sometimes the most meaningful shifts in life begin with something very simple:

Showing up.

Again…
and again…
and again.
Consistency.
Abhyāsa.
