The American Viniyoga Institute is the union of practitioners and institutions that base their practice in Viniyoga. As the site explains it, Viniyoga is “a comprehensive and authentic transmission of the teachings of yoga including asana, pranayama, bandha, sound, chanting, meditation, personal ritual and study of texts. Viniyoga (prefixes vi and ni plus yoga) is an ancient Sanskrit term that implies differentiation, adaptation, and appropriate application.” Gary Kraftsow developed the institute in order to tailor different methods and practices in yoga to individuals’ specific needs and conditions with a focus on back pain. The institute is based in Oakland, CA, but you can search for a teacher or therapist anywhere through the AVI website’s directory here.
