"If you pour a handful of salt into a cup of water, the water becomes undrinkable. But if you pour the salt into a river, people can continue to draw the water to cook, wash and drink. The river is immense, and it has the capacity to receive, embrace, and transform. When our hearts are small, our understanding and compassion are limited, and we suffer. We can’t accept or tolerate others and their shortcomings, and we demand that they change. But when our hearts expand, these same things don’t make us suffer any more. We have a lot of understanding and compassion and can embrace others. We accept others as they are, and then they have a chance to transform. So the big question is: how do we help our hearts grow?"
