When selfishness vanishes, all you want from life is to give. It is a constant source of joy. Not that you are blind to sorrow. Personal suffering is gone, but for that very reason there is no barrier separating you from the suffering of others. And that immense empathy releases intense action. "What one takes in by contemplation," Eckhart says, "one pours out in love." You live to give, to alleviate the sorrow and improve the lives of those around you, and in that giving is more joy than the world knows. It is the perfect fusion of the inward and outward currents of life, of meditation and action.
There comes a time when the world gets quiet and the only thing left is your own heart. So you'd better learn the sound of it. Otherwise you'll never understand what it's saying.
