Lacking a genuine identity we have to assume one (i.e., take it up, put it on). Such is education— from day one we learn what to assume. Because each must assume something. One cannot legally be nothing! This educated sense is the human assumption, which we put on each day. In fact, we have to assume our identity each moment, and only through this constant repetition does it become that perhaps all-too-familiar sense of 'ourself.'
Occasionally, the assumption can lapse, and it's strange how completely lost one can feel without it. It could even result in a panic attack. Not to mention complete unexcelled awakening.
