Every single negative thing we have ever thought or done has ultimately arisen from our grasping at a false self, and our cherishing of that false self, making it the dearest and most important element in our lives. All those negative thoughts, emotions, desires, and actions that are the cause of our negative karma are engendered by self-grasping and self-cherishing. They are the dark, powerful magnet that attracts to us, life after life, every obstacle, every misfortune, every anguish, every disaster, and so they are the root cause of all the sufferings of samsara.

-Sogyal Rinpoche
