"Just like muscles, our mental muscle, if you will, responds to exercise. It’s just which exercise you’re going to do.
One exercise relates to mindfulness, compassion, lovingkindness, having an open heart. And when you strengthen that muscle, the world becomes a vibrant place where you recognize the incredible aspect of humanity that surrounds you in every person, how every person has this incredible potential to change the world.
Or you can do a form of exercise that makes you afraid, that makes you pull away, that makes you think that people are your enemies, or that people are out for something. And, unfortunately, sometimes it’s an active choice, but for many people, they don’t even understand that this is happening."
