To meet someone who really hurts you, is to meet a rare and precious treasure. Hold that person in high esteem, and make full use of the opportunity to eradicate your defects and make progress on the path. If you cannot yet feel love and compassion for those who treat you badly, it is a sign that your mind has not been fully transformed, and that you need to keep working on it with increased application.

-- Dilgo Khyentse Rinpoche
