Maharshi Patanjali in Yoga Sutras

Maharshi Patanjali in Yoga Sutras has enunciated 8 limbs of yoga. Many people think that the eight limbs are eight steps, one after another. However, the limbs are not sequential; they are parts of the whole. It's like the human body. The whole body develops together. All the organs develop together, but at their own suitable pace. Patanjali also says that the purpose of yoga is to stop misery before it comes. Whether it is greed, anger, jealousy, hatred, or frustration, all these negative emotions can be healed or re-oriented through yoga.
