Yoga Beyond āsanas: Discipline, Renunciation, and Transformation on the Path of Ashtanga Yoga

There's a widely repeated phrase in the Yoga universe: “Yoga is not just posture.” And it's true.

āsanas are just one of the eight limbs of Ashtanga Yoga, a system presented by the sage Patañjali in the Yoga Sūtras. Within this path, āsanas occupy the third limb. In other words, they are just one part of a much broader philosophy and spiritual practice.

But there's a common mistake in interpreting this phrase as a way to diminish the importance of postures. Although they are just “the tip of the iceberg,” āsanas play an essential role in the practitioner's transformation process.

Practice as an instrument of transformation

In the second chapter of the Yoga Sūtras, dedicated to practice, Patañjali states in sūtra 2.43: “kāyendriyasiddhiraśuddhiksayāt tapasah”. Translated as:

“By the practice of self-discipline, impurities are destroyed and then the body and sense organs gain spiritual strength.”

This teaching reveals something fundamental: practice doesn't just exist to develop physical capabilities. It is an instrument of purification, presence, perception, and inner strengthening.

Yoga is sādhanā, that is: a spiritual practice. And Ashtanga Yoga, specifically, is a journey based on discipline, constancy, and devotion. A journey not everyone will have the disposition to sustain.

Over more than thirteen years of practicing Ashtanga Yoga, I have seen many practitioners extremely talented in āsanas give up before even experiencing something deeper from the practice. And this happens because the depth of Yoga doesn't emerge quickly. It comes from daily repetition, silent commitment, and perseverance over the years.

Many give up due to the difficulty of maintaining a consistent practice. Others, due to the complexity of the postures that gradually emerge in the method. There are also those who distance themselves due to a lack of careful, human, and empathetic guidance – and, in these cases, that's okay. Not every teacher suits every student, and not every student identifies with a particular environment or approach.

Daily practice is continuity

When I speak of discipline and daily practice, I don't necessarily mean performing the full sequence every day. I refer to the willingness to step onto the mat daily, even if it's just to breathe, chant mantras, practice Sūrya Namaskāra, do the fundamental postures, or simply observe one's own breath.

Daily practice is not about performance. It's about continuity.

And perhaps one of the most important questions on this path is: why are we not practicing? Is it truly an impossibility or, often, an escape?

In the first chapter of the Yoga Sūtras, in sūtra 1.30, Patañjali describes the obstacles on the path of Yoga: illness, apathy, doubt, inattention, laziness, lack of renunciation, mistaken perception, inability to sustain what has been achieved, and lack of continuity.

These obstacles are part of the path. The danger lies in constantly normalizing them or turning every difficulty into a justification.

Renunciation and purpose

Among these obstacles, there is one especially important: the lack of renunciation. And, sometimes, that's exactly what it's about: renouncing.

Renouncing extra hours of sleep. Renouncing habits that weaken the body and mind. Renouncing excessive late-night eating. Renouncing nightlife when it distances us from practice. Renouncing vices, excesses, and, above all, the mind's self-sabotage.

Of course, each person has their own goals, priorities, and circumstances. Not everyone wants to practice every day, advance through the series, or become a teacher. And that's okay. Everyone makes their choices consciously (or unconsciously) and lives with the consequences within their own practice.

In my case, tapas, which is understood as austerity, discipline, and inner fire, arises from my purpose with Yoga.

I practice to know myself. To take care of my body and mind. To heal myself. And also to continue my path as a teacher, transmitting a method that has profoundly transformed my life.

For me, it doesn't make sense to teach without this commitment to myself and to the people who choose to practice with me.
