But question is how to tame the mind ? Be mindful of breathing. In Yoga you have to change the breathing process. In mindfulness you have to be aware of the breathing as it is. Just be aware of it. If you can become aware of your breathing, then you can become aware of your thought process; otherwise not.
Those who try to become aware of their thought process directly will not be able to do it. It will be very arduous, tedious. Breathing is the door to the mind. If you stop your breathing for a single moment, your thoughts will also stop. When breathing stops, the thought process stops. If your thinking is chaotic, your breathing will be chaotic. Breathing will simultaneously reflect your thought process.
