A prayer by Saint Madeleine Sophie:

O Sacred Heart of Jesus, give me a heart that is one with Your own;
a humble heart that knows and loves its nothingness;
a gentle heart that holds and calms its own anxieties;
a loving heart that has compassion for the suffering of others;
a pure heart that recoils even at the appearance of evil;
a detached heart that longs for nothing other than the goodness of heaven;
a heart detached from self-love and embraced by the love of God,
its attention focused on God,
its goodness is its only treasure in time and in eternity. AMEN.
