There is no effort that we can make to still ourselves. True stillness comes naturally from moments of solitude where we allow our minds to settle. Just as water seeks its own level, the mind will gravitate toward the holy. Muddy water will become clear if allowed to stand undisturbed, and so too will the mind become clear if it is allowed to be still.
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.
