Uproot all passions and evils from our hearts through purity of heart and watchfulness
From the Philokalia, Saint Hesychios the Presbyter
If we preserve, as we should, that purity of heart or watch and guard of the intellect whose image is the New Testament, this will not only uproot all passions and evils from our hearts; it will also introduce joy, hopefulness, compunction, sorrow, tears, an understanding of ourselves and of our sins, mindfulness of death, true humility, unlimited love of God and man, and an intense and heartfelt longing for the divine.
