We ought to do all we can to crush and humble the heart. To achieve this we should scrupulously remember our former life in the world, recalling and reviewing in detail all the sins we have committed since childhood (except carnal sins, for the remembrance of these is harmful). This not only induces humility but also engenders tears and moves us to give heartfelt thanks to God. Perpetual and vivid mindfulness of death has the same effect: it gives birth to grief accompanied by a certain sweetness and joy, and to watchfulness of intellect.
