Yoga is a timeless and pragmatic science that evolved over thousands of years in India. It deals with the physical, mental, moral and spiritual well-being of human beings as a whole. The word yoga is itself derived from the Sanskrit word yuj, which means to join or attach. It also means union or communion, a true union of our will with the will of God. It is one of the means or techniques for transforming consciousness and attaining liberation (moksha) from karma and rebirth (samsara).
