"Yoga Body: The Origins of Modern Posture Practice"
2010, Oxford University Press
"In spite of the immense popularity of postural yoga worldwide, there is little or no evidence that asana (excepting certain seated postures of meditation) has ever been the primary aspect of any Indian yoga practice tradition
The primacy of asana performance in transnational yoga today is a new phenomenon that has no parallel in premodern times."
(page 1 of the Introduction)
"Singleton shows that, contrary to popular belief, there is no evidence in the Indian tradition for the kind of health and fitness-oriented asana practice that dominates the global yoga scene of the twenty-first century. Singleton's surprising and surely controversial thesis is that yoga as popularly practiced today owes a great debt to modern Indian nationalism, and even more surprisingly, to the spiritual aspirations of European bodybuilding and early 20th-century women's gymnastic movements of Europe and America, than it does to any ancient Indian yoga tradition."
