An insight made available to us by the hermit's life is that we are all, each one of us, a hermit; that in the end we know we are a unique creation of God, and alone because of that uniqueness, and that this alone-ness become solitude is the meeting place with God. This is true no matter how social and communal our exterior lives may be. It is within our interior solitude, the solitude and silence that many of us (including hermits) try to shut out with noise and activity of various sorts in order to evade that encounter, that we are called into truth and confrontation with mercy, that we are given what it is we have to give in our encounters with other people who in their own lives are engaged in the same searching.
Compassion is an aspect of Divine love that melts all defenses and resistance when anyone's suffering is really seen. There is nothing the personality can do to create compassion, but when we are willing to be completely open and truthful about whatever we are truly feeling, it arises naturally and soothes our hurt. (We could say that truth without compassion is not really truth, and that compassion without truth is not really compassion.) The Divine love that seeks to express itself in the world through us is a powerful force that can break through all of the old barriers and untruths that have accumulated in us.
