The "I" does not exist
We are struggling to make sure of the permanence, continuity, and safety of this enduring core, this corner and soul of our being which we call “I.” For this we think to be the real man – the thinker of our thoughts, the feeler of our feelings, and the knower of our knowledge. We do not actually understand that there is no security until we realize that this “I” does not exist.
