Once you begin to know the being behind the very pretty or very ugly face, as determined by your bias, the surface appearances fade away until they simply no longer matter.
God, who is the ground of all being, dwells in, around and through ALL things -- ultimately emerging as the real -- and any appearances that mask that reality will fall away.
In the book "The Shack" this was Jesus' response to Mack when Mack thought Jesus was "not very good looking." Jesus told him, 'If you knew me, it wouldn't matter how I look."
