The great joy of the solitary life is not found simply in quiet, in the beauty and peace of nature or in the song of birds or even in the peace of one's own heart. It resides in the awakening and the attuning of the inmost heart to the voice of God — to the inexplicable, quiet, definite inner certitude of one's call to obey God, to hear God, to worship God, here, now, today in silence and alone.

Thomas Merton, The Sound of Listening by John Dear
