How training the mind in following precepts, such as the rules regarding the use of four monastic requisites - food, robes, shelter, and medicines, can win us greater patience, faith, gratitude, calm, courage, and mindfulness. Such ways of renunciation test our commitment to the path and teach us how to forgive and let go even our fears so that we harvest the riches of joy, compassion and inner peace. A talk given during a Theravada Buddhist Community retreat in Toronto, 2008.
