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.
By our prayer we share the life of God. True prayer demands that we be more passive than active; it requires more silence than words, more adoration than study, more concentration than rushing about, more faith than reason. The highest state of prayer is to be children in the arms of Love: silent, loving, rejoicing.
