The first chapter
אֵין סוֹף
The Infinite Without End
Ein Sof is not the largest thing that exists. It is the name given to the failure of every boundary by which created thought attempts to hold its Source.
Infinity is not a quantity
Classical SourceWhen we say that something is infinite in ordinary speech, we usually mean that it is very large, or that it does not stop. Both of these are still descriptions of measurement. Something that never stops is still the kind of thing to which stopping could in principle apply. Something immeasurably large is still on the same scale as something small.
אֵין סוֹף does not work this way. The phrase is composed of a negation and a noun: there is no — end. It does not tell us how far the Creator extends. It tells us that extension is the wrong category. The term is not an answer to the question how much; it is the retirement of the question.
This is why the classical formulations reach so often for negation. The Essence is described by what cannot be said of it. The Tikkunei Zohar does not say that G-d is very great and very hidden; it says that no thought grasps Him at all — not partially, not distantly, not by approximation.
The reader should feel the difference immediately. A very large G-d would still be an object within reality, merely an enormous one. Ein Sof is not an object within reality. Reality is what happens inside the room He makes.
The Infinite is not another object inside reality. It is the name given to the collapse of every boundary by which created thought attempts to contain its Source.
One, but not in number
Classical Sourceאַתָּה הוּא חַד וְלָא בְחֻשְׁבָּן
You are One, but not in number.
Patach Eliyahu states the point with unusual precision: אַתָּה הוּא חַד וְלָא בְחֻשְׁבָּן — You are One, but not in the manner of a number.
A number is one member of a series. To be one numerically is to be the first of a possible two. It implies a scale on which one could stand alongside something else. Numerical oneness is therefore already a form of limitation: it locates.
Divine oneness is not the first term of a series but the absence of any series. It does not exclude a second G-d the way one apple excludes being two apples. It excludes the very framework in which a second could be counted.
Chassidus develops this into what is sometimes called the higher unity: not merely that there is no other god, but that there is no other existence in the sense of existence that stands on its own. Whatever exists, exists as something continuously receiving being.
Creation introduces no change in G-d
Chassidic Developmentאֲנִי ה׳ לֹא שָׁנִיתִי
I, the L-rd, have not changed.
If Ein Sof is genuinely without limitation, then creation cannot have added anything to Him, and cannot have subtracted anything either. A Creator who became different by creating would be a Creator with a before and an after, and therefore with a boundary in time.
The verse אֲנִי ה׳ לֹא שָׁנִיתִי — I, the L-rd, have not changed — is read in Chassidus not merely as a statement of faithfulness but as a metaphysical claim. The Divine reality is not altered by the appearance of worlds.
This has a consequence that is easy to state and difficult to hold: from the perspective of the Source, the emergence of creation is not an event. All of the drama of concealment and revelation happens on the side of the recipient, not on the side of the Giver.
The Chabad formulation is characteristically blunt: nothing has changed above; everything has changed below.
Nothing has changed above. Everything has changed below.
Continuous creation
Chassidic Developmentוְאַתָּה מְחַיֶּה אֶת כֻּלָּם
And You give life to them all.
Sha'ar HaYichud VeHaEmunah makes the further move. Creation is not an act completed in the past whose products now persist under their own power. Existence is continuously spoken. The letters of Divine speech that brought the heavens into being remain within them, at every moment, as the sole reason they are anything at all.
Withdraw that speech and there is no residue. Not ruins, not particles, not empty space. There would be nothing left to leave behind, because there was never anything whose existence was its own.
This is what transforms Ein Sof from a metaphysical abstraction into the most concrete fact about the room the reader is sitting in. The table is not an old object that G-d made long ago. It is a present utterance.
Atzmus, Ein Sof, Ohr Ein Sof
Chassidic DevelopmentChassidus insists on a distinction that is easy to blur, and blurring it produces most of the confusions that follow.
Atzmus — Essence itself. Not infinite as opposed to finite, because that opposition is still a pair of terms. Essence is prior to the distinction between limitation and limitlessness, which is why Chassidus can say the startling thing that Atzmus is no more restricted by infinitude than by finitude.
Ein Sof — the language of boundlessness. This is already a way of speaking, and therefore already an accommodation to a mind that needs terms.
Ohr Ein Sof — the Infinite Light. Light, in this literature, always means revelation: not the source, but what the source gives of itself. Everything that follows in the cosmology — tzimtzum, kav, worlds, sefirot — happens in the domain of light, not in the domain of Essence.
Boundlessness and nearness are the same fact
Classical SourceIt would be natural to assume that the more infinite a G-d is, the more distant He must be. Chassidus argues the reverse, and does so rigorously.
Distance is a relation between two bounded things. If Ein Sof has no boundary, there is no edge at which He ends and something else begins — and therefore no interval across which He would have to travel to be near. לֵית אֲתַר פָּנוּי מִינֵּיהּ, there is no place empty of Him, is not poetry. It is the direct consequence of boundlessness.
The verse in Devarim states both halves in one breath: ה׳ הוּא הָאֱלֹהִים בַּשָּׁמַיִם מִמַּעַל וְעַל הָאָרֶץ מִתָּחַת אֵין עוֹד — in the heavens above and on the earth below, there is nothing else. The above and the below are named, and then dissolved by the last two words.
אֵין עוֹד מִלְבַדּוֹ
There is nothing else besides Him.
