When we cast our bread upon the waters we can presume that someone downstream whose face we will never know will benefit from our action, as we who are downstream from another will profit from the grantor's gift.
We human beings are social beings. We come into the world as the result of others’ actions. We survive here in dependence on others. Whether we like it or not, there is hardly a moment of our lives when we do not benefit from others’ activities. For this reason, it is hardly surprising that most of our happiness arises in the context of our relationships with others.
. . . the integral being is attached to nothing and can relate to everyone with an unstructured attitude. Because of this, her very existence benefits all things.
It seems that most of us could benefit from a brush with a near-fatal disaster to help us recognise the important things that we are too defeated or embittered to recognise from day to day.
