Yoga is a dynamic system of physical exercise and a valuable philosophy to apply to everyday life.
The ultimate goal of yoga philosophy is complete detachment from reality, as we understand it, and complete self knowledge or Samadhi. This lack of self knowledge is thought to be the fundamental cause of many emotional and nervous problems. The word YOGA comes from Sanskrit language and means union. There are various Yoga systems but the goal is always the same, which as we have said, is perfect self knowledge. The most popular form of Yoga practised in this country is Hatha yoga which is concerned with body control and consists of a series of exercises or asanas.
