Works of Penance, Frequent Confession, Mortification, Almsgiving is by Father Francis Fernandez Carvajal from his series on meditations In Conversation with God, Daily Meditations Volume Two: Lent and Eastertide, 1.2:
True conversion is shown by the way we behave. We show that we really want to improve by the way we do our work or our study. We show it by the way we behave towards our family; by offering up to God, in the course of the day, little mortifications which make life for those around us more pleasant, and which make our work more effective. We can also show it by making a careful preparation for and going frequently to Confession.
Today God asks us also for a rather special mortification, which we offer up cheerfully: it is fasting and abstinence, which strengthens our spirit as it mortifies our flesh and our sensuality. It raises our soul to God. It gets rid of concupiscence by giving us the strength to overcome and to mortify our passions, and it disposes our heart that it may seek for nothing except to please God in everything.9
