Prayer has two wings. One is fasting and the other is alms.
"Lent...is a privileged time for prayer. St. Augustine says that fasting and almsgiving are 'the two wings of prayer,' which give it greater impulse to reach God. He states: 'In this way our prayer, made with humility and charity, in fasting and almsgiving, in temperance and the forgiveness of offenses, giving good things and not returning bad things, removing ourselves from evil and doing good, seeks peace and obtains it. With the wings of these virtues our prayer flies safely and is taken with greater certainty to heaven, where Christ, our peace, has preceded us' (Sermon 206, 3 on Lent: PL 38, 1042). "
