Fasting.

"Lent proposes three very helpful techniques for [healing our relationships with God and neighbour]. One is fasting. We inherited this practice from the Jews and share it with the Muslims and others. It is said to have many benefits: schooling the passions, reducing lust, resisting the devil, teaching temperance, helping appreciate more what we normally have. More recently, people fast for peace, to identify with the hungry, to take a stand against consumerism, to cleanse themselves of toxins or merely to lose weight. One way or another, fasting seems to help us get a handle on ourselves; to acknowledge our self-indulgence, our over-indulgence, our obsession with our own comfort; to confess that this diminishes us; and to co-operate with God in His project of healing our hearts. Fasting is good for our relationship with ourselves". - from the Lenten Message of Bishop Anthony Fisher OP.
