Mark Singleton is a scholar and practitioner of yoga. He studied yoga intensively in India, and became a qualified yoga teacher, until returning to England to study divinity and research the origins of modern postural yoga. His doctoral dissertation, which argued that posture-based forms of yoga represent a radical break from haṭha yoga tradition, with different goals, and an unprecedented emphasis on āsanas, was later published in book form as the widely-read Yoga Body.
