March 4 - Prayer to St. Casimir

O patron of the impoverished who though son of a king counted yourself among the poor in spirit, you whose love abundantly flowed to all in need, who sought the purity of our Blessed Mother, who thirsted for our Lord in the Blessed Sacrament, who devoted yourself to prayer and constant works of charity – teach us this day to be pure and set our hearts on serving the poor that we too might come to share the kingdom with all God's children, all those who empty themselves of the things of this world to find the grace of Heaven.
