…which He brings about through the Sefirot in accordance with the law He chose for them... When God acts through the Sefirot, it is not in accordance with His intrinsic omnipotence, whereby He can do everything in one command without the need to separate and differentiate between the various stages. When He chose to act through the Sefirot, He organized His powers in an orderly system, as stated in Brit Menuchah (a 15th century Kabbalistic text by Rabbi Abraham of Grenada). In other words, He chose to act little by little and to think about each thing individually. Not that He Himself has any need of this. He chose to act in this way because this is the way in which man can gain a modicum of understanding of God’s ways and His works.
