How could an Almighty God, creator of the worlds, let himself be put to death by his own creatures? Mystery. To designate this lowering, this humiliation, this annihilation of the divine, Christianity uses the word kenosis, from the Greek verb kenoô, « to empty oneself, to strip oneself, to annihilate oneself ». This word was first used by the Epistle of Paul to the Philippiansⁱ.

But the idea of God’s death is much older. It can be found in the centuries preceding Christianity in quite different forms, it is true, for example among the Greeks with the death of Dionysus killed by the Titans, but also among the Egyptians with the murder of Osiris and his dismemberment by Seth, his own brother.

Among Jews, with the concept of tsimtsum (from the Hebrew צמצום, contraction), there is also this idea of a « God who empties himself ». It is a concept of late appearance since it is due to Isaac Louria in Ari Zal (Safed, 16th century), who uses it to explain a point of Kabbalah :

Before the creation of the worlds, God was everything, everywhere, and nothing was without Him. But when God decided to create the worlds, he had to give them a place so that they could be. God withdrew his original light, or qadoum. In the void thus created, called reshimou (« imprint », from the verb rashama, « write ») a light emanated from God, or néetsal. This emanated light constitutes the olam ha-Atziluth, the world of Emanation. Then are generated the olam haBeryah or world of Creation, the olam haYetzirah or world of Formation and the olam haAssiya or world of Action, – which contains our world. The light emanating from it therefore undergoes several contractions, compressions, or « dissimulations », which are all tsimtsum.

This word comes from the verb צָמַם tsamam, which has a wide spectrum of meaning: « to put an end to, exterminate, silence, annihilate, compress, contract, squeeze, veil, hide, observe closely, define exactly, certify », which is described in Marcus Jastrow’s Dictionary of Targumim Talmud and Midrashic Literature (1926). From this rich range, the word tsimtsum probably brings out the harmonics.

Here are some of them, taken from a Kabbalah lesson by Baruch Shalom Alevi Ashlag. The reason why the emanated Light cascades through the four created worlds, Atziluth, Beryah, Yatzirah and Assiya, is that the « desire to receive » must at each step be increased accordingly. For there can be no divine creation without an equally divine desire to « receive » this creation.

In the beginning, there is an abundance of Light created, emanating from the divine essence. Correlatively there must be an abundance of desire to receive this light. But this desire to receive cannot appear in the world ex nihilo. Desire is itself created. It is called Kli ְכְּלִי , a word whose primary meaning is: « thing done, thing made ». It is also called, less metaphorically, Guf (« the body »). The Kli must « receive », « lock », « hold » the light in him (as the root verb כָּלַא indicates).

Here, a little aside. The Kli can be said to be a piece of furniture, a vase, a garment, a suit, a ship, an instrument or a weapon. Here again, all the harmonics of these various senses can undoubtedly be applied to make the Kli resonate in its role as a receptacle of light, – in its role as a soul, therefore. Sander and Trenel’s dictionary says that Kli comes from the root verb כֶּלֶה (kalah), a close word to ֶכָּלַא (kala’), already mentioned. The verb kalah offers an interesting spectrum of meaning: to be made, completed, ready; to be resolved; to disappear, to miss, to be consumed, to perish, to languish; to finish; to consume, to exterminate.

Believing that words serve as a memorial to millenary experiences, I would think that all these meanings apply in one way or another to kli in its possible relationship with light.

Divine light, falling into the different worlds, spreads and at the same time contracts, folds, or veils itself, to let the desire to be received by the Kli grow, by this receptacle, this desire, this soul or this « body », this Kli which is at the root of the created creature. The Kli, who was previously part of the Light, must now distinguish himself from it in order to receive it better; he must separate himself from it in order to desire it better. He desires it as Or Hokhma (the Light of Wisdom) or Or Haya (the Light of Life), or Or Hassadim (the Light of Mercy). The Kli is therefore determined according to the degree of expansion of the Light and also according to its degree of exit from it.

Wise men commented on these questions as follows: « There is crying in inner dwellings ».

This means that when the Light arrives in the lower worlds, and it does not find a Kli wishing to receive it, it remains « interior », unrevealed, and then « there is crying ». But when she finds a Kli who desires her, she can reveal herself on the outside, and then « vigour and joy are in His place », and everything becomes visible.

i Ph. 2, 6-9 ^{« Lui, de condition divine, ne retint pas jalousement le rang qui l’égalait à Dieu. Mais il s’anéantit (εκένωσεν) lui-même, prenant condition d’esclave, et devenant semblable aux hommes. S’étant comporté comme un homme, il s’humilia plus encore, obéissant jusqu’à la mort, et à la mort sur une croix !  Aussi Dieu l’a-t-il exalté et lui a-t-il donné le Nom qui est au-dessus de tout nom. »}
