Once we recognize that other sentient beings - people, animals, and even insects, are just like us, that their basic motivation is to experience peace and avoid suffering, then when someone acts in some way or says something that is against our wishes, we’re able to have some basis for understanding: “Oh, well, this person (or whatever) is coming from this position because, just like me, they want to be happy and they want to avoid suffering. That’s their basic purpose. They’re not out to get me; they’re only doing what they think they need to do.”
Compassion is the spontaneous wisdom of the heart. It’s always with us. It has always been, and always will be. When it arises in us, we’ve simply learned to see how strong and safe we really are.
