These "Divine Praises" are often recited after Benediction of the Blessed Sacrament and before the Holy Eucharist is returned to the tabernacle. They were composed by the 18th century Jesuit Louis Felici in reparation for blasphemy and profanity.
If you have trouble with cursing or saying "Oh my G-d" in vain, you might commit yourself to reciting these divine praises every day to train your tongue in holiness.
