When it rose upon His simple desire (30) to create the worlds and emanate the emanated beings to bring the perfection of His deeds, His names and appellations to light, which was the reason of the creation of the worlds (Study of the Ten Sefirot, Part 1, Chapter 1).
Question: Does this mean that the Creator created worlds and created beings to show the perfection of His actions?
Answer: Basically, yes. The Creator created the worlds and created beings in order to reveal His perfection and the perfection of His actions to the created beings who would be able to attain His actions and through them to attain Him.
The Creator Himself is concealed, He is unattainable. Only His actions are attainable because He reveals Himself in them. Through His actions we can imagine who He is, although the very essence of the Creator is unattainable to us.
