St. Thomas Aquinas
Grant me, O merciful God, ardently to desire the things that are pleasing to Thee, prudently to study them, truthfully to acknowledge them and perfectly to carry them out to the praise and glory of thy name. Put my house in order, O Lord, and grant me to know what thou dost require me to do; grant that I may then do it for the salvation of my soul.
O Lord my God, grant that I may not fail in prosperity and adversity so as not to be inflated by the one nor depressed by the other. Let nothing gladden me or sadden me except what leads me to Thee or separates me from Thee. May I desire to please and fear to displease no one but Thee.
Let all passing of earthly things cheapen in my sight, O Lord, and all eternal things be precious. Let joy that is without Thee bore me and let me not desire anything outside of Thee. May the labor that is for Thee, O Lord, delight me; and all rest that is without Thee weary me.
Grant me, O Lord my God, to direct my heart to Thee and ever to sorrow for my sins and make amends for them.
Make me, O Lord my God, obedient without any back-talk, poor without abjection, pure without puritanism. Make me patient without repining, humble without being a fraud, happy without being fractious, mature without being a bore, keen without being frivolous; let me fear Thee without despair, be truthful without double-talk; let me do good without presumption, correcting my neighbor but not pompously, supporting him by work and example without flattery.
Give me, O Lord, a watchful heart which no curious thought can wean from Thee; a noble heart which no unworthy affection can seduce; give me a righteous heart which no sinister intention can twist away from Thee; a firm heart which no tribulation can break; a free heart which no violent affection can claim for itself.
Grant me, O Lord God, intelligence to know Thee, diligence to seek Thee, wisdom to find Thee, conversation to please Thee, perseverance faithfully to await Thee and confidence finally to embrace Thee.
Grant me, that through penance I may accept Thy punishments, through grace I may employ Thy blessings and through glory enjoy Thy heavenly delights. Who livest and reignest God forever and ever. Amen
