Sutras are thought threads followed in Raja Yoga. These are around 4000 years old which are practices by Yogis to achieve highest level of physical, mental and spiritual excellence. Sutras cover the yoga teachings on ethics, meditations, asanas, prayanamas, dhautis and mudras etc. and provide directions to a yogi for dealing with issues and problems in daily life. We will provide detailed information on  195 Yoga Sutras of Patanjali in our subsequent posts.
