Don't associate with any one who is afflicted with jealousy even at the cost of your life. Jealousy is the worst of all evil qualities. Three-fourths of the world is ruined because of jealousy. It is very dangerous to cultivate association with people of evil traits. Even a little contact with them can pollute you with their evil qualities.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
