And I saw this in your response. I will explain these matters briefly, for they are the essence of my letter. How can we assume the En Sof and the other close faces to the En Sof, and still worship the intermediate? Your response was that the other attributes include both judgment and mercy, and this intermediate encompasses them all.
And for this reason, the Emanator desired to manifest His actions through this instrument, and so forth. I will provide you with an analogy from the physical hand, which performs all the tasks, whereas the head, which is positioned above, does nothing. Even the power of speech, which is a glory, and so forth - all your words are but words of wonderment! I asked you about their statement that the "other-than-He" is our God and Him we shall serve, and you respond to me regarding the actions they perform willingly.
But should we worship all those who act willingly? And you claim that they are our God? Isn't it the sun that performs many good actions for us, such as illuminating, warming the air and the earth, causing vegetation to grow, and ripening fruits? Should we worship them too?
The moon and the stars also act below according to the will of the Creator, as it is written: "From the choicest produce of the sun and from the choicest yield of the months." Should we worship them as well? The earth, the water, and the fire also act to make vegetation and trees grow and nurture them. And with fire, we fulfill all our desires to bake and cook all our food.
In many crafts, we inflate coal in fire and shape tools for their purposes. Should we worship any of them? And His will is to perform His actions through simple and evident means, as described in the Scriptures. The waters will flow, giving life to the living creatures; the earth will produce vegetation, and it is said that His messengers are winds and His servants are flaming fire, and so on and so forth, in every aspect of His delegated tasks.
And despite all this, the Almighty commanded us to serve Him alone and warned us not to worship any other besides Him. At the chosen moment of His revelation during the exile on Mount Sinai, His voice resounded before His entire assembly, saying, "I am the Lord your God; you shall have no other gods before Me." And it is said: "I am the Lord; that is My name! And My glory I will not give to another."
You and I stood before the Creator, who made us, and He did not desire that we worship any other, even though He has appointed agents to perform certain actions. Why should we not heed His voice and go worship that which He did not command us to worship?
