These captions and lecture slides are a quick tour through yoga’s formal and intellectual developments in the the Modern Era. They are from the presentation “Iyengar’s Guru and the Birth of Modern Yoga.” For folks in Yoga Alliance certified teacher-trainee programs, presentations like these make learning easy, and convey the latest scholarship about the practice freshly. Other modules include “Where Yoga Poses Come From,” “Shamans and Showmen: Yoga as Tantra,” “Transformations of the Tradition: Ancient to Modern,” “Ancient and Modern Science Behind Yoga Postures and Practices,” “Yoga Philosophies: Samkhya and Advaita Vedanta,” “A Short Introduction to Sanskrit,” and “Patanjali’s Yoga Sutras.”
