To All My Teachers, Known and Unknown

When the student is ready ... the teacher appears

Guru Purnima and The many gurus who quietly shaped my life.

There comes a stage in life when you realize that learning never really ends. As children, we are taught to respect our teachers. As young adults, we seek mentors who help us navigate careers and relationships. Later in life, we discover something even more profound—that the world itself becomes our classroom.

This Guru Purnima, I find myself reflecting on a simple thought:

Everyone is my teacher.

Some I consciously seek and some I subconsciously attract.

Some I learn from simply by watching how they live, love, struggle, forgive, create, or persevere.

Many of them may never even know they have taught me something. Yet I bow deeply in gratitude.

That, perhaps, is the true spirit of Guru Purnima.

More Than a Religious Festival

Observed on the full moon of the Hindu month of Ashadha, Guru Purnima is one of India’s oldest celebrations of wisdom. It is also known as Vyasa Purnima, honoring Maharishi Veda Vyasa—the sage who compiled the Vedas and authored the Mahabharata, preserving timeless knowledge for generations.

For Buddhists, this same full moon commemorates the day Gautama Buddha delivered his first sermon at Sarnath, setting in motion the wheel of Dharma. Jains, too, honor their spiritual teachers on this day. Across traditions, the essence remains beautifully consistent: Knowledge is sacred. Those who illuminate our path deserve our gratitude.

Guru Purnima To All My Teachers, Known and Unknown

But Who Is a Guru?

As children, the answer seemed obvious.

A guru was the teacher standing at the blackboard.

Or perhaps the music teacher patiently correcting every note.

Or a spiritual master guiding seekers towards enlightenment.

Life has expanded that definition.

Today I see gurus everywhere.

A colleague who quietly demonstrates integrity when no one is watching.

An entrepreneur who teaches resilience after every setback.

A child whose curiosity reminds us to ask questions we have stopped asking.

An elderly parent who teaches acceptance.

A friend who listens without judgement.

Even those who hurt us often become our greatest teachers. They reveal our own expectations, attachments and capacity to forgive.

Sometimes life itself becomes the guru.

The Most Unexpected Teachers

Looking back, many of my greatest lessons did not come from books.

They came from moments.

Pandemic taught me that health is never something to postpone appreciating.

Business challenges taught me that uncertainty is not the opposite of success—it is often part of the journey.

Parenthood taught me that love also means learning to let go.

Indonesia has been one of my greatest teachers. Living here for decades has shown me how cultures can coexist without losing their identity. It has taught me patience, humility and the beauty of building bridges between communities.

Every person we encounter carries a story we know nothing about. If we pay attention, almost every encounter leaves us wiser.

Why Guru Purnima Matters More Than Ever

We live in an age overflowing with information. Artificial intelligence answers our questions within seconds. Social media offers advice from thousands of voices and knowledge has never been more accessible.

Wisdom, however, remains something entirely different. Wisdom cannot simply be downloaded, and needs to be cultivated through experience, reflection, humility and the willingness to remain a student.

Perhaps that is why Guru Purnima feels even more relevant today than ever before.

Not because we lack information, but because we need discernment.

The Sanskrit word Guru is often explained as “the one who dispels darkness.” A guru is not merely someone who gives answers; a guru helps us see more clearly, challenges our assumptions, and awakens us to a deeper truth.

This timeless aspiration is beautifully expressed in one of the oldest prayers from the Brihadaranyaka Upanishad:

asato ma sad gamaya

Isn’t that what every true teacher does?

Whether it is a parent, a schoolteacher, a spiritual master, a friend, or even a difficult life experience, each one gently nudges us from ignorance to understanding, from fear to courage, from self-centeredness to compassion. Every lesson, however small, becomes another step towards the light.

Sometimes that light comes through a teacher.

Sometimes through adversity.

Sometimes through silence.

A Quiet Practice of Gratitude

This year, instead of asking, “Who is my guru?”

I invite you to ask a different question.

Who has changed the way I see the world?

Reach out to them with a message, a phone call or a note. Or simply remember them with gratitude.

Not everyone who teaches us stands on a stage.

Some teach through kindness, courage and some through their failures.

Some simply through the way they live.

The Journey Never Ends

One of the greatest gifts of growing older is recognizing how little we truly know and how freeing it is to remain a lifelong student.

Curiosity keeps us young and humility keeps us learning, while gratitude keeps our hearts open.

On this Guru Purnima, I bow not only to the teachers whose names I remember, but also to the countless souls who unknowingly shaped my journey.

Everyone is my teacher.

Because every encounter has the potential to move us—from ignorance to understanding, from fear to courage, from self-centeredness to compassion.

And perhaps that is the greatest lesson of all.

Happy Guru Purnima.
