Yoga is an ancient science that aims to create a balance between the body, mind and soul, thereby curing physical mental and spiritual disorders that are caused by this imbalance. In common language, yoga means union; it's a union of the individual consciousness with the super-consciousness. To be exact, yoga aims at reminding the individual of this union that already exists and has merely been forgotten. To put it simply, yoga is experiencing and knowing what already exists, not inventing anything new.
At the physical level, yoga can create a balance and harmony among the various organs and systems of the body, allowing the healing powers inherent in the body to work and cure physical ailments. At the mental level, yoga is the harmony between mind, heart and hands or between thought, speech and action. At the spiritual level, yoga aims to destroy the individual ego that stands between the individual and the cosmos, thus attaining to the ultimate truth.
