“Sorrow works in two ways: it is like water because it quenches all the fire of passion with tears and washes the soul clean of stains, and it is like a fire which gives life by the presence of the Holy Spirit. It kindles, blazes up, and warms the heart, and inflames it with love and desire for God.”
+Symeon the New Theologian
I really like your quote about sorrow working in two ways.
First the cleansing of the heart; then the lighting of the heart for good, love and action.
