We human live a life using our mind. But we know so little about the mind and it's potential, that all our life we look for solution to our problems from someone, somewhere or simply give up. Original Yoga from Ancient Indian Culture is the Science of Mind. Maharshi Patanjali has explained about the mind so well in his book - Yoga Sutra. He has not just explained, he also wrote how you can systematically follow the path of Yoga and start to control your mind then use all its potential. If you are interested to go and achieve higher stages of mind, he has also explained what sadhana needed.
