This episode holds a special place for me because …it is my 50th interview! and it feels deeply appropriate that this milestone is shared with Prashant Iyengar.

From the very beginning of this podcast, Prashantji has been a guiding presence. His generosity with his time, his willingness to engage in these conversations, and his continued support have made this work possible in ways I don’t take lightly. This podcast, in many respects, lives in the space he continues to illuminate.

Rooted in the teachings of B.K.S. Iyengar, On the Light has always been about listening more deeply—to the method, to the tradition, and to the voices that carry it forward. And Prashantji sits right at the center of that living tradition.

In this summative episode on sangeet— He reminds us that while forms may evolve over time, the essence remains untouched—like the sun behind an eclipse, or a diamond beneath layers of dust.

Prashant speaks to the importance of preserving the source of the tradition, even if only a very small number continue to carry that work forward. And I find myself reflecting that this podcast, in its own small way, is part of that effort—to listen, to learn, and to help keep that thread alive.

It is an honor, and truly a privilege, to share this 50th conversation with him.

Welcome to On the Light. I’m your host, Susan Johnson.

In this episode I am deeply honored to be in conversation with Eric Small—a pioneering teacher of Iyengar Yoga whose work has spanned more than six decades.

Iyengar and Geeta Iyengar, as well as his groundbreaking work adapting yoga for students with multiple sclerosis. Through storytelling, reflection, and lived experience, he shares what it means to teach from the heart, to observe deeply, and to serve with humility.

This conversation is both a historical record and a personal testament—offering insight into the early years of Iyengar Yoga in the West, the depth of the teacher-student relationship, and the enduring power of practice as a path of healing and self-understanding.

Welcome to On the Light. I’m your host, Susan Johnson.

Today I’m joined by longtime Iyengar Yoga teacher Mary Reilly. Mary began practicing yoga in the early days of Iyengar Yoga in the United States, studying with teachers who had just returned from India after working directly with B.K.S. Iyengar. What began as a simple attempt to regain her concentration after finishing a demanding biology degree quickly became a lifelong path of practice and study.

In this conversation, Mary shares what it was like to encounter Iyengar Yoga in its early years, her first trips to Pune during the intensive programs at the institute, and the profound lessons she absorbed from Guruji and Geeta Iyengar. We also talk about the art of teaching, including Mary’s memorable experience participating in the filmed teaching demonstration known as The Art of Teaching in Chicago.

Along the way, Mary reflects on listening with the body, trusting the intelligence of practice, and what it means to teach from the heart rather than simply from the mind.

Welcome back to On the Light. I’m your host, Susan Johnson.

Today, it is my great honor to speak with Gloria Goldberg, a longtime student and teacher of the Iyengar method, whose decades of dedicated study and service have placed her in direct contact with Guruji, Geetaji, and the Iyengar family for many many years.

Gloria’s journey began in the early 1970s, when she was first drawn to yoga as a way to manage her asthma. What began as a simple, personal practice soon became a lifelong path—one that led her to study in Pune, assist in organizing conventions, help develop teacher education programs, and serve the Iyengar community with extraordinary devotion.

In this conversation, Gloria shares intimate memories of her time with Guruji and Geetaji, reflections on practice as an experiential and transformative process, and the profound responsibility of preserving and transmitting this work to future generations.

Welcome back to On the Light. I’m your host, Susan Johnson.

In today’s episode, I’m grateful, as always, to sit down with Prashant Iyengar for another conversation that takes us deeper into the subject of Sangeet.

Prashant begins by explaining that Sangeet arises from the Natya Shastra — the ancient Indian treatise on dramaturgy and the performing arts, a text that explores music, dance, theatre, rasa, and the inner mechanics of expression itself.

From there, he leads us into a profound reflection: that life itself is a kind of drama.

We are not the roles we play.
Father, mother, friend, student — these are enactments.
Costumes. Movements within a larger unfolding.

And the Self, he reminds us, is beyond all of it.

Welcome back to On the Light. I’m your host, Susan Johnson. Today I’m joined by Devki Desai.

Devki’s journey with Iyengar Yoga began in Mumbai in the mid-1980s, when her father first brought her to class as a teenager. What began with some resistance soon became a lifelong path, shaped by early study with senior teachers and, soon after, direct exposure to B.K.S. Iyengar himself. Over the years, Devki’s life became deeply interwoven with the Institute in Pune—through practice, teaching, family, and seva.

In this conversation, Devki shares intimate stories of being guided and trained by Guruji, Geetaji, and Prashantji —three influences she never separates, but experiences as a woven whole. She reflects on learning to teach through direct instruction, observation, and responsibility; on being “thrown into” classes as a form of training; and on the grace that carried her through those formative years.

She also speaks movingly about pranayama, motherhood, devotion, and the subtle ways yoga shapes a life over time.

This is a conversation rich with memory, lineage, and lived experience, and I’m so grateful to share it with you.
