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.
This is one of the things that love is called upon to do:
To affirm and sustain the seed in another human being even though no tangible evidence has been given of the nature and quality of the seed that is growing there. Love depends upon the capacity to reach beneath the surface of persons, to feel and touch the seed of life that is hidden there. And love becomes a power when it is capable of evoking that seed and drawing it forth from its hiding place.
