That which is at the center of the Sacred Space within my heart,
is the very same which is in the sun, which is in the earth,
in the heart of every living being.
~ from Chandogya
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.
