The Sefirot of which we speak are parts of the interconnected order in which the Supreme Will organized His creative activity, similar to the way in which a person thinks his thoughts little by little and carries them out stage by stage. This being the case, it is possible for us to understand how many powers are involved in each individual act: which was first, which came afterwards, how it acted, and so on. It would have been completely impossible to talk in such terms if Eyn Sof, blessed be He, had wanted to act in His omnipotence. His acting little by little is like a person who knows how to read a complete word all at once yet chooses to read each letter individually in the way that children do.
