Musar su Geremia 10:10

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.

The soul is created from the place of the Holy Spirit, as it is said, "And breathed into his nostrils the breath of life" (Gen. 2:7). And it is hewn out from a place of purity, and it is created from the supernal radiance, from the Throne of Glory. And in the realm above, in the place of the Holy of Holies, there is no falsehood. There everything is truth, as it is said, "But the Lord God is the true God" (Jer. 10:10). I have found written, "I am that I am" ^** Hebrew: Eheyeh asher Eheyeh. (Ex. 3:14). And it is also written, "And the Lord God is the true ^**** Hebrew: emet. God, He is the living God and everlasting king" (Jer. 10:10).

In support of this statement is the verse, "But the Lord God is the true God, He is the living God, and the everlasting King" (Jer. 10:10). And if a man does not speak anything but the truth, he will be free all the days of his life, as it is written, "The law of truth was in his mouth, and unrighteousness was not found in his lips… "For he is the messenger of the Lord of hosts" (Malachi 2:6—7). The angels above are in the form of truth, and they are not in physical form. The souls of men give light like the light that goes from the sun. Now the souls are in bodies, therefore they know only a little of the secret things and then only in the visions of the night. For the souls do not occupy themselves with the needs of the body, and he who knows the secret of the soul will testify to this. Now dreams are very much like thoughts, as it is written, "Thy thoughts came (into thy mind) upon thy bed" (Dan. 2:29). And dreams come about through an angel who accompanies man, and just as all thoughts are not true, so all dreams are not true. And he who accustoms himself that all of his thoughts are true, then even in the night he will see visions of truth, and he will know future things, just as the angels do.
