My yoga teacher made a profound statement one day in class. She said yoga is mostly unseen. I have been reflecting on this statement. Yoga generally has three main components, They are breathing, asanas, concentration/awareness. Asanas are externally observed and others can see it. Breathing is a technique and can be observed if the teacher looks at you closely. In a large class it is is difficult how well and correctly the students are breathing. But, the most important part of yoga, being aware and focused is totally unseen by the instructor or others. Only, the student practicing yoga knows it.
