Karl Erb, one of San Francisco’s senior yoga teachers, learned in May of 2010 that he had cancer.  Rather than retreat from the world, Karl shared his experience; strength and hope via his blog inspiring people the world over. As Karl prepares to return to teaching, he offers his reflections on getting sick, facing his mortality and coming through the other side by turning to his years of yoga practice for strength, courage and inspiration.   Resources Karl’s WebsiteBook: The Empathetic Civilization by Jeremy Rifkin
