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.
Birds inspire and uplift us with their carols... In the muslc of both birds and humans, beauty is "the wine which overflows." When the last lark has fallen silent, something holy will have vanished from the world. The chorus of life will be muted. The cathedral of the earth will have lost its choir.
