O omnipotent Father, God of truth, God of love, permit me to enter into the cell of self-knowledge. I admit that of myself I am nothing, but that all being and goodness in me comes solely from You. Show me my faults, that I may detest my malice, and thus I shall flee from self-love and find myself clothed again in the nuptial robe of divine charity, which I must have in order to be admitted to the nuptials of life eternal. Amen.
Prayer by Catherine of Siena, which I consider a prayer against personal narcissism. Classic painting of St Catherine of Siena's mystical marriage to Christ was executed by Giovanni di Paolo.
