Reading about nature is fine, but if a person walks in the woods and listens carefully, he can learn more than what is in books, for they speak with the voice of God.
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.
