In the end... there is one, and only one thing that can be given (up) by us... and that is the false sense of self born of having become identified with something. The amazing thing is... that since whatever one is identified with doesn't exist without one having first imagined it... this means one's sense of self -- created by one's attachment to the image -- must be equally imagined. To understand this properly is to begin seeing the Truth that sets one free: the only thing one has to surrender in this life is... the illusion that one has anything real to surrender at all.
