Yoga, an ancient but perfect science, deals with the evolution of humanity. This evolution includes all aspects of one's being, from bodily health to self-realization. Yoga means union — the union of body with consciousness and consciousness with the soul. Yoga cultivates the ways of maintaining a balanced attitude in day-today life and endows skill in the performance of one's actions.
