“Our well-fed bodies decay and emit an offensive odor after death, whilst theirs [ascetics] remained fragrant and flourishing in life as well as after death. It is a wonderful thing: we, by building up, destroy our body; whilst they, by destroying, built up theirs; they, by only caring for the fragrance of their souls before God, obtained the fragrance of their bodies also.”
(St. John of Kronstadt in ‘My Life in Christ’)
