as the outward manifestation of the psyche, it is nothing more than a necessary mask. its destruction leaves one open to predatory nature of those about you and only a fool or a saint would leave themselves defenseless in this hostile world. i'm pretty sure you're not the latter and i can only hope you're not the former. of course, an obsession with one's ego is unhealthy, but its absence is equally so. perhaps you should attempt to control your ego before you go preaching about the need for its destruction.
