Pesukei D’zimrah: Baruch Sh’Amar: Hidden & Revealed

The Gra (Haggadah: Baruch HaMakom) explains that when we recite the words, “Blessed is He Who spoke, and the world came into being; blessed is He.” We are blessing both the revealed and the hidden. The specific praise of, “Who spoke, and the world came into being,” refers to the world we see and can comprehend. The praise, “Blessed is He,” refers to all that is hidden in the creation, and cannot be described.

This idea of “Hidden and Revealed,” refers to the worlds of “Thought and Action.” We referred to what we see as Action, and to what we cannot see, as Thought.

This teaches us that when singing this song of praise we must remember that there are two levels to each of the Ten (Explained by the Abudirham as corresponding to the Ten Statements with which the world was created) praises we recite; the Hidden–Thought, and the Revealed–Action.
