Groping for a transcendent word in a vocabulary generated by our physical lives, we seize upon “light.” Light is our metaphor for the incorporeal, the spiritual, the Divine. We speak of an era of “enlightenment” dispelling dark ages of ignorance and ignominy, of a “ray” of hope penetrating the blackness of despair, of the Divine “light” that bathes the virtuous soul.
Light straddles the defining line that runs between the physical and the spiritual. Sans weight, sans mass, sans just about any of matter’s properties, light is the most ethereal of physical “things.” Perceptibly real, yet free of the qualities we ascribe to the objects of our perceptible universe, light serves as a bridge of allegory between a mind grounded in a material environment and the metaphysical abstractions it contemplates.
In the Tanya, Rabbi Schneur Zalman of Liadi employs the metaphor of light to explain what is perhaps the most radical truth expressed by the Torah: the inexistence of the universe.
Twice in Chapter 4 of Devarim (verses 35 and 39) the Torah makes this amazing statement. “You were shown to know that G‑d is the G‑d, there is none else beside Him . . . Know today, and take unto your heart, that G‑d is the G‑d, in the heavens above and the earth below, there is none else.”
The ever sensible mind may perhaps interpret these verses to mean that there are no gods other than Hashem. “I,” the mind will insist, “the body I occupy, the table it is sitting at, and the computer screen I am looking at certainly exist. These verses, then, are only affirming the basic tenet of Judaism—that there is but a single, singular Creator and ruler to the universe.”
Not so, say the Kabbalists and the Chassidic masters: “there is none else” means that there is none else. Indeed, they explain, to maintain that there are existences other than G‑d is ultimately the same as maintaining that there are other “gods” beside Him. What real difference is there between saying that the universe is governed by thousands of gods, or by a god of good and an equally potent god of evil, or by a very powerful god who (almost) always triumphs over a much weaker Satan, or by a great and mighty god who pervades every iota of existence save for a single cubic centimeter of space? Ultimately, one is saying that there is more than one independently potent force in existence. To say that there is a god with the power to create and destroy universes, punish the wicked and reward the righteous, and cause galaxies to spin and crops to grow, but that there also exists a single pebble with a power independent of His—be it only the power to exist—is to deny His exclusive divinity and power.
So when the Jew daily declares, “Hear O Israel, G‑d is our G‑d, G‑d is one,” this is more than an affirmation that there is but one deity. It is a statement on the inexistence of all else save His one being.
Real In Relation
Yes, we perceive our own existence and the existence of the myriads of objects and forces we call “the universe.” But this is our finite and subjective perception of reality. If we could observe reality from the all-transcendent perspective of the Creator, we would see a “world” devoid of selfhood and being. In the words of the Tanya: “If the eye were allowed to see the life and spiritual content flowing from the utterance of G‑d’s mouth into every creation, we would not see the materiality, grossness, and tangibility of the creation, for it would be utterly nullified in relation to this Divine life-force . . .”
Modern physics demonstrates the relativity of apparent absolutes such as time and space. An object or event cannot be said to possess an intrinsic size or duration—these are always a matter of perspective. The same object may be an inch in length as observed from point A, and a hundred miles long as observed from point B; the same event can be said to transpire over the course of a second or a thousand years, again depending on the position and velocity of the observer. The mind may have to bend over backwards to assimilate a vision of reality so radically different from its first-hand experience of its environment, but every high-school science student has read of the experiments and seen the diagrams that demonstrate this truth.
But the Torah has a more demanding task for the mind: to comprehend the relativity of existence itself—to understand that even the very “I” that is making the observations are also a matter of perspective, and that while the created reality perceives itself as real, there is a higher perspective from that reality, the truth that “there is none else beside Him.”
Where, in our experience of the universe, is there an example of this sense-defying truth, an analog that may aid us in achieving this tremendous leap of mind? What model have we for the relativity of a thing’s very existence? Light.
Light exists. We regard light as an entity distinct of its emitter, distinguishing between a luminous body and its luminescent expression. An observer on Earth, for example, perceives both the sun and the light that extends from it, and hence our dictionary includes both the term “sun” and “sunlight.” But what would be the perspective of an observer within the sun? Would he, too, perceive “sunlight” as an existence distinct of the sun? Obviously not. Light, by definition, has a source and a destination, an emitter and an observer; light is information—a communication from one thing to another. Light, then, exists only in relation to that which is outside of its source, but not in relation to the source itself. If sunlight is defined as “the sun’s luminescent expression” then it cannot be said to “exist” within the sun, where the very notion of “expression” is superfluous and meaningless.
Does this mean that the entity we call light “begins” outside of the sun? Again, the answer is obviously not. The sun itself is not dark; the luminescence that extends from it certainly pervades it. It is just that the concept of “light” has validity and meaning only to an observer outside of the light’s source. Lacking substance of its own, light exists only insofar as it serves its function: to carry information and effect from its emitter to that which lies outside its emitter. Where it has no function (i.e., within its emitter), it does not exist—not because it is any less “there,” but because it lacks the context that defines its existence.
Light, then, both exists and does not exist at the same time, depending on the context in which it is viewed. It goes from non-existence to existence not by undergoing any intrinsic change but simply by being observed from a different vantage point—a point in relation to which its function has significance.
So, explains the Tanya, light is the metaphor through which we can try to understand the relative existence of the universe. Our world is “light” emitted by G‑d: an expression of His omnipotence and a revelation of His majesty. (Thus, light is the first creation, and the exclusive creation of the First Day, for light is existence in its most basic form.) As “light,” the created reality has no substance of its own and no intrinsic being; its “existence” is defined solely by its function—to express and reveal its Emitter. So the world exists only as observed from without its Creator and Source. As seen from G‑d’s perspective, it does not merit the term existence—again, not because it is any less “there” (G‑d, after all, tells us in His Torah that He created a world) but because in relation to the Divine “sun” the defining function of the sunlight of creation is utterly insignificant.
(Rabbi Schneur Zalman takes this a step further, pointing out an important difference between the sun/sunlight analogue and the Creator/creation relationship it illustrates. With the sun, we identify two distinct areas in whose context the “existence” of sunlight is considered: outside the sun, and within the sun. Outside the sun, sunlight exists; within the sun, it is non-existent. Regarding the Al‑mighty, however, the existence of this “second perceptive” is also only a matter of perspective. In truth, there is no “area” that is outside of G‑d’s infinite reality; the “vacuum” into which G‑d emanates His light is a vacuum of perception, real only from our mortal perspective. In other words, G‑d did not create a reality outside of Himself, but only the perception of a reality outside of Himself. So the “light” of creation is, in truth, “sunlight within the sun”—that is, non-existent light. To us, the world exists only because we perceive ourselves as being “outside of the sun”—a perceived vantage point from which “sunlight” is perceived as an “existence.”)
The View From Sinai
As cited above, the Torah twice reiterates the exclusivity of G‑d’s existence, twice in the same chapter proclaiming that “there is none else” other than Him. For there are two paths by which man may come to appreciate the nature of his reality vis-à-vis the Divine: from the top down, and from the bottom up.
The first verse (Devarim 4:35) is referring to the day that “G‑d descended on Mount Sinai” in a unilateral revelation of His all-pervading truth. On that day, Moshe reminds the assembled community of Israel 40 years later, “You were shown to know that G‑d is the G‑d, there is none else beside Him.” On that day you were raised above the arc of your subjective vision of self and existence and accorded a glimpse of reality from His perspective.
The revelation at Sinai was a brief “foretaste” of a future world—a world in which all masks and superimposed “perceptions” will fall away. A world in which “your master shall no longer shroud Himself; your eyes shall behold your Master”; a world in which “the world shall be filled with the knowledge of G‑d as the waters cover the sea” (Yeshayah 30:20 and 11:9). The world of Mashiach—when, as the Zohar puts it, “G‑d will take the sun out of its sheath” and obliterate the concealment that effects the perception of a reality outside of His.
Bracketed between the revelation at Sinai and the revelation of Mashiach, we live in a world in which our Master does shroud Himself—a world in which the sun remains sheathed and we are not “shown to know.” It is regarding this world that the Torah enjoins us, in the second verse cited above, to “know today, and take unto your heart” that “in the heavens above and the earth below, there is none else.” The knowledge is there, embodied in the heavens above and the earth below: in every blade of grass, in every sunset, in the depths of our minds and in the sublimity of our hearts. In this world the onus is upon us to unearth this truth, comprehend it, and incorporate it into our hearts and lives.
This explains the difference between these two verses. When we are shown the Divine truth, there are no details and no mention of “the heavens above and the earth below.” As viewed from the supernal perspective, the particulars of creation fade to insignificance. One does not even see the distinction between the spiritual (“the heavens above”) and the material (“the earth below”)—only the singular truth that “there is none else beside Him.” But when our quest begins from the bottom up, it is precisely these details and distinctions that build our knowledge and appreciation of the Divine truth. The more we delve into creation’s components, the more we recognize them as rays of Divine luminescence. We recognize that creation is “light,” an existence defined not in terms of self-being but as the bearer of a higher truth. ϖ
