William Bi: William turned to yoga in 2000 when he wanted to boost his rock-climbing, his passion at the time. Over time he climbed less and was drawn to yoga's spiritual depth beneath the physical demand.

William became a teacher after training programs with Yoga in Motion in and Stott Pilates school in Canada. Desiring deeper yoga and Buddhist practices, he left Canada in 2004 and moved to India and Thailand.

William's main teachers are Yogacharya V. Venkatesha, a strict South Indian yogi, who taught him devotion and discipline; Ajahn Sona, a Theravada monk in Canada who led him to find his ease; his countless stumbles which remind him that yoga is to strive and to surrender.

The posture of yoga is steady and easy. It is realized by relaxing one's effort and resting like the cosmic serpent on the waters of infinity. Then one is unconstrained by opposing dualities. -Patanjali, Yoga Sutra, Part II
