According to the Yogapedia; “…Yoga is a physical, mental and spiritual practice that originated in ancient India. It became popular in the West in the 20th century. The word, yoga, comes from the Sanskrit yuj, which means “to yoke” and “samadhi” or “concentration.” Thus, yoga is the practice that aims to join the mind, body and spirit. The ultimate goal of yoga is to achieve liberation.
Yoga has been practiced for thousands of years and, over the years, many different interpretations have developed about what yoga means. Each different type of yoga has its own emphasis and practices.”
