When one gives completely, there is no one left to watch what is being given, and no one to appreciate how generous one is being. This is called “giving the giver.” The more one surrenders in this way, the more richness develops. There is never a problem of running out of things to offer. One’s human life is in itself an immensely rich situation to offer.
