One has to see oneself through one's actions, works, and mind. Knowing the Self by the self is not as easy as writing that line. A # yogi sees things in every movement he makes, maybe when practicing, maybe when teaching, or maybe when talking to people. You should have courage in your convictions and pursue what is dear to you all these years.
