In order to produce an actual effect, all the supernal lights must enter into the category of letters. The letters constitute a complete order that exists to bring all things into actual being. This is the meaning of the verse: “...and through the word of God the heavens were made” (Psalms 33:6). For speech exists only in virtue of the letters of which it is made up.

Having explained what the Sefirot are, we now turn to the letters of the Hebrew alphabet with which they are associated, as discussed by the Kabbalistic sages.
