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

My guest today is Nikki Costello, a longtime student and teacher of Iyengar Yoga. Nikki reflects on her first encounters with Light on Yoga, her studies with Mary Dunn and Gulnaz Dashti, and the profound experiences that shaped her understanding of the teachings at the Ramamani Iyengar Memorial Yoga Institute in Pune.

Along the way, Nikki shares stories of Guruji and Geetaji that illuminate not only their brilliance as teachers, but also the depth of care, discipline, and transformation that lie at the heart of the guru-disciple relationship. She speaks about lineage, mentorship, oral tradition, and what it means to carry the teachings forward—not as a collection of techniques, but as a living practice that continues to evolve within each of us.

This is a conversation about transmission, responsibility, and the enduring vitality of the teachings.

Welcome back to On the Light and to what is now our fifth season. I'm your host, Susan Johnson.

My guest today is Jaki Nett Jaki is one of the recipients of the Lighting the Way Award presented by IYNAUS in recognition of her decades of dedication to the study, practice, and teaching of Iyengar Yoga. Jaki received this honor at the recent IYNAUS Convention in Philadelphia.

In this conversation, Jaki reflects on nearly four decades of study in Pune, her deep and enduring relationship with Geeta Iyengar, and the profound influence Geetaji had on her life as a student, teacher, and practitioner. She shares stories of both Guruji and Geetaji that reveal not only their brilliance as teachers, but also their humanity, humor, compassion, and unwavering commitment to the subject of yoga.

At its heart, this is a conversation about lineage—how it is received, how it transforms us, and the responsibility each of us carries to preserve and pass on the teachings with integrity.

Welcome to Light on Cooking: The Iyengar Tradition. I’m your host, Susan Johnson

In this opening conversation, Prashant Iyengar reflects on the role of food within the life and culture of Yogacharya B.K.S. Iyengar—not simply what was eaten, but the deeper philosophy surrounding food, discipline, ritual, timing, silence, and awareness.

What unfolds is far more than a discussion about meals or favorite dishes. Prashantji offers a rare glimpse into the atmosphere of the Iyengar household: food prepared by family members, meals taken in silence, eating as an offering rather than consumption, and the profound relationship between nourishment and practice.

He speaks about sattvic food, the discipline of mealtimes, Guruji’s simplicity and moderation, and the understanding that yoga does not end on the mat, but extends into every aspect of daily life. The conversation moves between philosophy, culture, memory, and lived experience, revealing how even the most ordinary acts can become sacred when approached with awareness.

This episode sets the tone for the series itself: an exploration not only of cooking and food traditions, but of care, consciousness, family, and the subtle ways yoga is woven into everyday living.
