“To understand that there is no security is far more than to agree with the theory that all things change, more even than to observe the transitoriness of life. The notion of security is based on the feeling that there is something within us which is permanent, something which endures through all the days and changes of life. We are struggling to make sure of the permanence, continuity, and safety of this enduring core, this center 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.”
