What to Expect: The inspiration for many vinyasa-style yoga classes, Ashtanga Yoga is an athletic and demanding practice.

What It's About: The practice is smooth and uninterrupted, so the practitioner learns to observe whatever arises without holding on to it or rejecting it. With continued practice, this skill of attentive nonattachment spills over into all aspects of life. This is one important meaning of K. Pattabhi Jois's famous saying, "Practice, and all is coming."
Teachers and Centers: Founded by K. Pattabhi Jois (1915-2009), this system is taught around the world. Jois's grandson R. Sharath now leads the Shri K. Pattabhi Jois Ashtanga Yoga Institute in Mysore, India. There are teachers everywhere around the globe.
