Musar for Numbers 24:11

Maimonides, in his ספר המדע writes as follows: "We must appreciate a fundamental truth, something basic to all knowledge. There is a SINGLE original Cause who in turn has created all other phenomena. If you ever were to think that HE does not exist, it would follow that none of the phenomena we perceive exist either. If you could imagine that all other phenomena would cease to exist, HE still would continue to exist, since all phenomena need Him for their continued existence, whereas He does not need them for His existence. His "truth" is therefore not comparable to any other kind of "truth," and this is why the prophet says: וה' אלוקים הוא לבדו אמת, "And the Lord G–d is truth" (Jeremiah 10,10). This is also what the Torah means in Deut. 4,35 ואין עוד מלבדו, "There is no one else beside Him." No truth exists independent of G–d. It is His Existence that is the supreme G–d of the universe, and He guides the universe. It is a positive commandment to acquire knowledge of and guard these facts, for the Torah says: "I am the Lord your G–d, etc." Anyone who entertains the thought that there is any other deity is a כופר בעיקר, violates a fundamental negative commandment, because the Torah says: "You must not have any other god in My Presence." Such a person denies the central pillar of the Jewish faith that everything depends upon Him. Thus far Maimonides.
