Remember that whenever you look without and react unfavorably to what you see, you have judged yourself unworthy and have condemned yourself to death. The death penalty is the ego’s ultimate goal, for it fully believes you are a criminal, as deserving of death as God knows you are deserving of life. The death penalty never leaves the ego’s mind, for that is what it always reserves for you in the end. Wanting to kill you as it’s final expression of feeling for you, it lets you live but to await death. It will torment you while you live but it’s hatred is not satisfied until you die. For your destruction is the one end toward which it works, and the only end with which it will be satisfied.
~A Course in Miracles
Just as kusha grass wrapped around rotting fish will soon begin to smell the same,
A person who associates with bad friends, in time, will certainly come to resemble them.
Shun unvirtuous friends who have bad characters, cynical outlooks, and prejudice,
Believe their own view to be the best, are boastful, and disparage others.
~The Treasury of Knowledge, Buddhist Ethics
