Mindful Yoga or Mindfulness Yoga combines Buddhist-style mindfulness practice with yoga as exercise to provide a means of exercise that is also meditative and useful for reducing stress. Buddhism and Hinduism have since ancient times shared many aspects of philosophy and practice including mindfulness, understanding the suffering caused by an erroneous view of reality, and using concentrated and meditative states to address such suffering. The use of a hybrid of yoga and mindfulness for stress was pioneered by Jon Kabat-Zinn in America in 1990. It has since been advocated in differing forms by yoga and meditation teachers and authors from many backgrounds, such as Anne Cushman, Frank Jude Boccio, Stephen Cope, Janice Gates, Cyndi Lee, Phillip Moffitt, and Sarah Powers. Courses in Mindful Yoga are provided in Buddhist meditation centres, yoga studios, and stress clinics around the world. The teacher of Mindful Yoga Anne Cushman notes that Hatha yoga and Buddhist meditation are branches of the same Indian contemplative tradition. In her view, asanas are both objects of meditation, and useful for preparing mind and body for sitting meditation, while Buddhism offers a formal structure of meditation techniques and philosophy that can exploit the "sensitivity, concentration, discipline and energy cultivated during asana practice." In his 2006 book The Wisdom of Yoga, the psychotherapist and yoga scholar Stephen Cope examines the overlap of Patanjali's raja yoga and Buddhism. He notes that both were mainly concerned with "the problem of suffering, and the problem of seeing reality clearly." Both traditions provided three sets of tools: techniques for cultivating skilful behaviour to reduce suffering; techniques to develop intense states of concentration; and ways of investigating how the "self" is constructed by the mind. Both recognise "ordinary reality" as a confusing mental construction, as modern constructivism does, Cope writes. They agree that abolishing such confusion of thought permanently ends suffering.
