That person in the mirror is just the outside, your earth suit; the real you resides on the inside

Discipline yourself to be a disciple of great works and to do that excellently, you have to wave "bye-bye" to some things and then switch off your inner person not to go near them again!

What good is there in being blind, you ask? Well, maybe it's to see the beauty on the inside without being vainly distracted, or superficially blinded, by the ugly on the outside.
