Further explanation can be added [to clarify the connection] between [the approach of] “I will choose the king” and the love [of G‑d] intimated by the verse, “Whom have I in heaven [but You]?” — i.e., that one desires G‑d’s Essence alone:

The fundamental [error] that led to the worship of the stars and the constellations1 is that primacy is attributed to something that [was intended to be] merely an intermediary. [This leads to a twofold misunderstanding:]

a) with regard to the stars and constellations themselves. In truth, they are merely an intermediary (an ax in the hand of the Chopper)2 through which the influence is conducted. Nevertheless, those who serve the stars and the constellations attribute primacy to them.

b) with regard to the material influence that is drawn down through them. The entire purpose [of G‑d granting] material influence is that it be used for one’s Divine service. Those who serve the stars and the constellations give primacy to the material benefits themselves. (Therefore, they choose to receive the influence of the nether side so that they will have an abundance of material influence, as explained in sec. 4 above.)

[A similar misunderstanding motivates one who seeks the revelations of G‑dliness in the spiritual realms.] The purpose of all Divine revelations, even the most lofty, is not [self-contained]. [The revelations do not shine forth] for their own sake. They are merely intermediaries through which G‑d’s inner intent for a dwelling in the lower realms is fulfilled.3 Therefore, when a person seeks these [spiritual] revelations and gives primacy to them (and not G‑d’s Essence), there is a possibility that he will give primacy to other intermediaries (the stars and the constellations, and material benefit).4

On this basis, it is possible to explain [the underlying rationale as to why, as stated in the Midrash cited at the outset,] there are those among the nations of the world who serve the sun and those who serve the moon, while Israel serves only the Holy One, blessed be He. The source for the existence of the nations of the world is the external dimension of G‑d’s will (one wants something [not for its own sake, but] for the sake of something else).5 The aspect of the external dimension of His will (that serves as the source for the existence of the nations of the world) is expressed in a manner that does not appreciate that this [external] desire is for the sake of something else,6 but rather [thinks of] itself as the ultimate purpose.7 Therefore, as a consequence [of being so created,] the nations of the world give primacy to [the intermediaries, i.e.,] the stars and the constellations.8

The source of the Jewish people, by contrast, is rooted in the inner dimension of G‑d’s will — and from the perspective of the inner dimension of G‑d’s will, there is no possibility for any matter other [than G‑d’s will to exist].9 Therefore the Jewish people recognize that [the intermediaries, i.e.,] the stars and the constellations, are like an ax in the hand of the Chopper (and similarly, the material influence [received] is solely for the sake of Divine service). Therefore they serve only G‑d, [declaring] “I will choose the King.”
