Final in Deed, First in ThoughtBut in this, too, there seems to be a prevalent view: That the entirety of the created existence, from the most sublime spiritual entity to the most corporeal creature, was created so that physical man should implement the Divine will in the physical world by observing the mitzvot of the Torah.
It is to this end that the soul of man, which the Zohar describes as "carved out of the heavenly throne of G-d" descends to earth to assume a physical body, character and life. It is to this end that the Torah, which originates in the heavens, has not only been revealed on earth but has been given over to man; after Sinai, the Torah "is not in heaven" but in the hands of its earthly students and observers (Deuteronomy 30:12; see Talmud,
Bava Metzia 59b).
The following passage in the Talmud says it all:
When Moses went up to heaven, the angels said to G-d: "What is a human being doing amongst us?" Said He to them: "He has come to receive the Torah." Said they to Him: "This hidden treasure, which was hidden with You for nine hundred and seventy-four generation before the world was created, You wish to give to flesh and blood? ... Place Your glory upon the heavens!"
Said G-d to Moses, "Answer them."
Said [Moses]: "Master of the Universe! This Torah that You are giving to me, what is written in it? 'I am the L-rd Your G-d who has taken you out from the land of Egypt.' Have you been brought down to Egypt?" asked Moses of the angels, "Have you been enslaved to Pharaoh?
"What else does it say? 'You shall have no alien gods'---Do you dwell amongst idol-worshiping nations? ... 'Remember the day of Shabbos'---Do you work? ... 'Do not swear falsely'---do you do business? ... 'Honor your father and your mother'---Do you have parents? 'Do not kill,' 'Do not commit adultery,' 'Do not steal'---Is there jealousy between you? Do you have an evil inclination?" (Talmud, Shabbat 89a).
The Midrash puts it this way: "G-d desired a dwelling place in the lowly realms." He desired that there be a realm that is lowly and distant from Him, a world that is inhospitable to His presence--in other words, a mundane, physical world--and that man transform this world into an abode for His manifest presence. "This is what man is all about, this is the purpose of his creation and of the creation of all the worlds, supernal and ephemeral," writes Rabbi Schneur Zalman of Liadi in his Tanya.
So the objective of creation lies in our earth-bound existence. Indeed, it is to this very purpose that G-d first created the spiritual heavens: so that they yield a physical world that is a "descendant" of a higher, more G-dly reality, and that thereby possesses the potential to transcend its lowliness and corporeality and become a "dwelling" that houses and expresses the Divine.
Which comes first, the heavens or the earth? In sequence, the heavens; in essence, the earth. That much is clear. So what is the dispute between the School of Shammai and the School of Hillel?
