This is the fasting that I wish: releasing those unjustly bound, untying the thongs of the yoke of oppression, sharing bread with the hungry, sheltering the homeless, and clothing the naked. Fasting is one of the three practices that characterize our Lenten observance. It is a rich practice that can be obscured by our too literal an understanding of what fasting is. Why do we fast and what do we fast from? We always think of fasting from food, and we do so to observe a commandment of the Church. However, fasting has a much broader scope than food, and our Lenten fasting should reflect this. The Lord, speaking through prophet Isaiah in our first reading today, could not have said it any better. 
In our list of priorities, self-preservation and happiness tops the list. In our list of people to love, we occupy the first place. We want better jobs, better neighborhoods, better cars, better schools for our children, and better treatment. This is not in itself bad. God does want us to be happy. God does want us to lead a good life. God wants the best for us. However, in our attempts at looking after our own good and happiness, we sometimes end up hurting others. This happens because in the pursuit of our own interests, we lose track of who we are and what we are about (the purpose for which God created us and put us in the world). We forget about the existence of the other as we become blinded by our attempts at self-preservation. This is what happens whenever I utter a word that aims at putting the other down; whenever in my attempt to beat the red light I overtake the other vehicle on the wrong side; whenever in my laziness I refuse to take the shopping cart in the designated spot and opt to leave it in the parking slot. 
Lent is a time for taking stock of our lives. It is time for slowing down in order to pay attention to my surrounding, a time to realize those brothers and sisters of mine who in my busyness had become invisible. Lent is a time for recollection, a time to reflect on my life and see in what areas I have been selfish and refused to live as a member of a community. Fasting helps me to remedy my acts of selfishness. Lent calls on me to fast (desist) from acts of selfishness such as refusing to forgive those who might have wronged me. Lent calls upon me to desist from engaging in bribery and similar corrupt acts that lead to oppression of the poor. Lent is a time of fasting from words that kill the happiness of others as well as words that cause discord in the community. Lent is a time of fasting that aims to build. This is the kind of fasting that the Lord requires from us.
