David Swensen is an ashtanga yoga teacher whose book and practice dvd have been a delight to me and useful! So I'm specially looking forward to attending a workshop with him at Camyoga. It's on the topic of how fine asana practice is open to everybody when we respect both our abilities and our limitations. And move in harmony with key lines through space. It will be great to meet someone whose teaching has mattered to me. Will let you know how it goes!
