When someone is suffering and you find yourself at a loss to know how to help, put yourself unflinchingly in his or her place. Imagine as vividly as possible what you would be going through if you were suffering the same pain. Ask yourself: “How would I feel? How would I want my friends to treat me? What would I most want from them?”
When you exchange yourself for others in this way, you are directly transferring your cherishing from its usual object, yourself, to other beings. So exchanging yourself for others is a very powerful way of loosening the hold on you of the self-cherishing and the self-grasping of ego, and so of releasing the heart of your compassion.
