Heart of Jesus, worthy of all praise, have mercy on us.

First a definition: Praise is the form of prayer which recognizes most immediately that God is God. It lauds God for his own sake and gives him glory, quite beyond what he does, but simply  because HE IS.  (Catechism Catholic Church 2639)

Second an example: While the Bible is filled with examples of the Praise of God, this one verse from the Psalms has both a literal sense and an anagogical sense:

  “I will bless the Lord at all times, his praise shall be continually in my mouth.” (Psalm 34:1)

The literal sense teaches us to praise the Lord every day, and through out the day, while the anagogical sense shows us that we are meant (taught by the Psalm) to praise the Lord Jesus Christ for all eternity.
