Yoga is an ancient discipline which originated in India thousands of years ago. Traditionally yoga is part of the 6 Schools of Thought (shad darshana) of the Indian tradition: Nyaya, Vaisheshika, Samkhya, Yoga, Purva Mimamsa, Vedanta. The term yoga derives from the Sanskrit root yuj, which means to unite, to yoke. It is essentially a philosophical quest to trace back men’s origin and re-unite with the Universal Self, from which we emanated. Its aim is therefore the union of the individual soul (jivatma), the essence of every human being, with the universal soul (paramatma) the origin of the entire creation. Unlike philosophical schools based mainly on speculation yoga is an experiential philosophy. This means that the practitioner needs to perform specific techniques to attain its aim. A specific methodology is also required as well as a strict observance to a set of rules which regulate every aspect of life.
