You are the sole witness, the Self of the nature of Consciousness. There is nothing else but you. Everything that seems to exist is only a reflection in you, as in a mirror. In the final chapter, this truth resounds as the last word. There is nothing more to add, nothing to explain, nothing to debate. The sākṣī that was a teaching in chapter 11 is now lived reality. What was mirror and reflections is now only Consciousness, without any possible division.
