It has been made clear that God’s entire purpose in creating the universe is to give pleasure to His creatures. That is, they will recognize the truths of God and His greatness and will receive from Him all of the good and the pleasantness that He has prepared for them, as explained based on the verse, “Is Ephraim not a precious son to me?” Therefore, it is equally clear that inanimate objects cannot achieve this goal.
Neither can celestial bodies (no matter how brilliant and large), plants, or even animals. All of these lack empathy, even for creatures that are similar to themselves. How could they appreciate God’s gifts and His goodness? Only humans [can achieve the goal of creation], since they have the potential for empathy toward those who are similar to them – particularly after the service of Torah and mitzvot, which transforms the desire to receive into a desire to give, thereby equating their form with that of their Creator.
After that, they receive all of the levels prepared for them in the upper worlds of NaRaNḤaY, which prepares them to receive the goals embedded in the plan of creation. In short, man is the purpose of the creation of all the worlds.
