This vigorous practice produces intense internal heat that creates a stronger body, a detoxifying sweat and a calmer mind.It was developed by K. Pattabhi Jois during the 20th century and is often promoted as a modern-day form of classical Indian yoga. Ashtanga means eight limbs or branches, of which asana or physical yoga poses is only one. It is the inspiration for most Vinyasa and Power Yoga styles.
