Teacher Mentoring

“Teachers must always be learning.”
-B.K.S. Iyengar, The Tree of Yoga

Before endeavoring to teach Yoga, one must have a firm foundation of Sadhana encoded into one’s cellular being. Practicing Iyengar Yoga both in weekly classes and on one’s own, consistently and over a period of two years (minimum), is a prerequisite for mentorship.

The Program

This course has been designed to support your transition from practitioner-only to practitioner who teaches other practitioners. By attending this program and committing to the course of study you will:

  • Refine your understanding of your own asana practice, which is the firm foundation of clear, effective teaching born from direct experience.
  • Learn the art of demonstration, instruction, observation and refinement and hone these important teaching skills.
  • Expand your understanding of yoga philosophy through the study of classical yoga texts and Mr. Iyengar’s writings so it becomes woven into the fabric of your life and your teaching.
  • Study basic anatomy and physiology and learn primary modifications of postures for common conditions (including menstruation) for the Introductory syllabus (Level 1).

The course will cover all of the required knowledge for both Level 1 and Level 2 certifications.

It is designed as a continuing education and mentoring program for students who are interested in teaching, those who are currently teaching and those preparing for assessment at both Level 1 and Level 2.

Those who are considering preparing for Level 1 assessment by IYNAUS are encouraged to take the course for two years. Students are also strongly encouraged to assist a certified Iyengar teacher as preparation for certification if possible.

The Teacher

Taught by Level 3 certified teacher Holly Walck Kostura, this program of study is an opportunity to deepen your commitment to practice and your personal relationship to the philosophy of Yoga.

Holly assisted Joan White in her classes and teacher training at the B.K.S. Iyengar Yoga School of Central Philadelphia for many years. She has been mentoring teachers from around the world since 2010. Holly has devoted more than half of her life to Iyengar Yoga Sadhana and is dedicated to preserving the commitment to excellence in teaching and to promoting the power of Iyengar Yoga practice in her local community and beyond. She was one of the youngest women to receive the title of “Senior Teacher” by the Iyengar Yoga Association of the United States (IYNAUS), having successfully passed all six assessment examinations under the previous system of certification.
