One of the world's foremost practitioners and instructors of Ashtanga yoga, David Swenson first journeyed to Mysore, India in 1977. He became one of the first Westerners to have learned the full Ashtanga vinyasa system as originally taught by K. Pattabhi Jois, including pranayama and all of the asana sequences. But his journey actually began in Houston, Texas in 1969, when David and his brother Doug taught themselves yoga out of books.
