Spirituality author Sarah Ban Breathnach writes, in her 1996 Simple Abundance Journal of Gratitude: "Gratitude bestows reverence, allowing us to encounter everyday epiphanies, those transcendent moments of awe that change forever how we experience life (is it abundant or is it lacking?) and the world (is it friendly or is it hostile?)." A Milton quotation occurs on the same page.
