Acharya Prashant addresses a question about the mysterious opening of the Upanishad. He explains that one can call it a mystery or an exalted, bold, uninhibited expression of one's deepest desire. He poses the question of who these verses are addressed to, stating that this is a very important question, without which the verses would never disclose their meaning. The word "Upanishad" itself means the event that happens in nearness, proximity, or intimacy. It is the mind that is the seeker, the one to whom the verses are addressed. The mind is seeking knowledge, relief, peace, and light. The mind is seeking the nearness of freedom, clarity, or Truth. The phenomenon in which the mind is coming close to the Truth is called an Upanishad. In the world of the mind, there is always discontent, dissatisfaction, and a continuous lack of fulfillment. For the mind, there is never fullness. Therefore, when the mind is told, "This is full, that is full," it is totally against the principle and experience of the mind. The mind has never seen any fullness. However, because the words are coming from an authority, the teacher, the mind has to listen and receive. The statement "This is full, that is full" indicates that everything is full, which the mind cannot believe. It is something novel, path-breaking, and extremely out of the mind's box. Fullness is a stranger to the mind; all-pervasive fullness is not even imaginable. The verse continues, "Fullness comes forth from fullness." This implies that if one cannot see fullness all around, it is because one does not have fullness within. The concluding blow is, "Take away fullness from fullness, and what remains is still full." This is so jarring and contrary to all that we call common wisdom or usual experience that the student's mind is jerked to a stop. The teacher has said something so unbelievable that the student cannot let it pass and must pay attention. In this way, the teacher has already delivered the entire message in the opening peace chant itself. Whatever the teacher says after this is just an elaboration for the student who is not yet ready to grasp the initial statement. The teacher has to speak a lot because the students are not ripe enough to get the answer in the first hint.
