“Exalt the Lord our God and bow before His holy mountain, for the Lord our God is holy.”
“Exalt” means that if one wants to know the exaltedness and greatness of the Creator, we can obtain this only through Dvekut [adhesion] and equivalence of form. Thus, what is “equivalence of form” and how does one achieve equivalence of form?
“Bow before His holy mountain.” Bowing means surrendering. It is when one lowers his reason and says that what the reason understands or does not understand, I annul and subjugate it. Before which quality do I subjugate it? Before “His holy mountain.”
Har [mountain] means Hirhurim [reflections], meaning thoughts. “His holy,” for “holy” means separated from the matter. This means that he removes himself from the desire of reception. “Bow” means submitting the body, even though it disagrees, and taking upon oneself only thoughts of Kedusha [holiness]. This is the meaning “Bow before His holy mountain.”
Why must we submit ourselves to thoughts of Kedusha, meaning retire from receiving in order to receive? It is because “The Lord our God is holy,” for the Creator only bestows. For this reason, one must be in equivalence of form with the Creator, and by this we can obtain the exaltedness of the Creator. Afterward, we can achieve the attainment of the exaltedness of the Lord our God.
