“Hrdaye citta samvit” (sutra 3.35) and ” Maitri Karunaa” (sutra 1.33). These two sutras were dear to Mr. Iyengar’s heart. At the final evening event for the IYNAUS Convention, Boca Raton, Florida, May, 2016, Leslie Freyberg and Jarvis Chen lead the participants in chanting two beloved sutras from the Yoga Sutras of Patanjal.
