Yoga means to connect to the spiritual through control of the mind, body and senses. The tradition of Yoga was developed by the Indus-Sarasvati civilization in Northern India over 5,000 years ago. The sacred texts of yoga, such as the Bhagavad-gita address the essential questions of life. There are a broad variety of Yoga schools, each with different practices and goals. Of the 8 limbs of Yoga, the physical postures called Asana gained significant prominence in the West in the late 20th century.
