The following are examples of actions that meet one of the conditions for gaining a partial indulgence (also see question 214):

(a) If one of the faithful, while doing his duty and bearing the burdens of life, lifts his heart to God with humble trust, adding, if only mentally, a pious invocation; or (b) if he, with a spirit of faith and a merciful heart, puts himself and his goods at the service of his brethren in need; or (c) if he, in a spirit of penitence, spontaneously, and with sacrifice, deprives himself of some lawful goods.
