This is true with regards to the worlds in general that Hashem chooses the lowest of all the worlds and this is also true with regards to this world itself that Hashem extends his ‘Atzmus’ into the most simple of things within this world.
It can be said that this is also why at ‘Matan Torah’ the Torah says: "Hashem spoke all of these things Leimor" that the word ‘Leimor’ here means: “in order that they shall say”, that the actual physical materialism and the very created beings of the lower realm itself will themselves become ‘Sayers’, meaning that their very existence itself is the cause that brought Hashem’s ‘Atzmus’ down here into this world. In other words, the reason why Hashem’s ‘Atzmus’ is drawn down into the actual physical materialism and the created beings of the lower realm is because they are the created beings of the lower realm and the actual physical materialism itself.
And this is the meaning of the Possuk when it says: "All the people saw etc, and the people saw and trembled; so they stood from afar" which resembled a receptacle so as to be able to draw down G-dliness.
