If we just worry about the big picture, we are powerless. So my secret is to start right away doing whatever little work I can do. I try to give joy to one person in the morning, and remove the suffering of one person in the afternoon. If you and your friends do not despise the small work, a million people will remove a lot of suffering.
Silence is really vital for the human heart. You see, the human heart can't live with constant sound or noise. It needs silence in order to heal itself. The only two things that are ultimately required for spiritual homecoming are stillness and silence. If, into your day, you can build little windows of silence and little windows of stillness, you will never lose touch with your deepest voice. You will never lose touch with your most secret belonging. Even though you walk and talk and act in the world, you will never leave the inner, tender home of your own soul.
