What is yoga?

"Yoga teaches us to cure what we don't have to bear, and bear what can not be cured." B.K.S Iyengar


The word yoga comes from the Sanskrit root Yug meaning to bind, to join, to direct, to concentrate, to use and to practice. It also means union or communion.



One of the main principles of yogic philosophy is Ahimsa, non-violence towards all living beings. Then how can one say he is practicing yoga, without being a vegetarian?
