The Superiority of Man to the Beast
After all the research, we find no advantage of man’s form over the beast except for the awakening towards Godly Dvekut (adhesion). It follows that the whole meaning of humanity’s existence is evaluated by the strength of man’s aspiration to the Creator, and in that, he is superior to the beast.
This is why it is written, “a wild ass’ colt is born a man.” And as the beastly desires necessary for his sustenance arise in man, so do the human desires need to awaken in him necessary for the fulfillment of his purpose. And the type of desires helps us discern who stands before us: still a beast or already a human, meaning he who craves similarity to the Creator.
