Nachum of Chernobyl
Rabbi Menahem Nachum Twersky — The Me'or Einayim
He looked at the world and saw it differently than most: not matter interrupting spirit, but spirit wearing matter's face. The light he found — in a blade of grass, in a merchant's calculation, in an enemy's spite — was not metaphor. It was the literal radiance of Ein Sof, the divine Infinite, present in every particular thing and act without exception. His great work, the Me'or Einayim, is not a systematic theology but a perceptual training: a guide to developing eyes that can see what has always been there.
Anatomy of the Titles
Lineage Position
Nachum held a rare position among second-generation Hasidic masters: he had received transmission from both the Baal Shem Tov and the Maggid of Mezeritch — sitting at the confluence of the founding fire and the systematic theology. This double receipt gave the Me'or Einayim its distinctive quality: the doctrinal precision of the Maggid's school in service of the Besht's uncompromising immanentism.
Nachum came to the Baal Shem Tov as a young man and absorbed the founder's central conviction: that God is not merely present in the world but is the world's only true substance, and that the experience of divine separation is the fundamental illusion that spiritual practice dissolves. He then spent years with the Maggid of Mezeritch after the Besht's death, receiving the theoretical architecture — the language of Tzimtzum, the chain of worlds, the doctrines of divine sparks and their elevation. What emerged was his own synthesis: a theology of light that was simultaneously more poetic than the Maggid's and more rigorous than mere piety.
When Nachum settled in Chernobyl and began leading a community, he established something that would outlast him by centuries. His son Mordechai and his eight grandsons each became Rebbes in different towns, scattering the Chernobyl transmission across Ukraine in what became one of the most geographically extensive Hasidic dynasties — the Twersky family, still active in the United States and Israel today.
Five Teaching Pillars
The Me'or Einayim is a commentary on the weekly Torah portion, but beneath the particular readings runs a consistent set of structural commitments. These five themes define Nachum's place in the tradition and distinguish his contribution from that of his contemporaries.
The Light Within Everything
Where the Maggid had developed the Baal Shem Tov's immanentism into a theological system, Nachum pressed it into application. His question was not whether God is present in all things — that was established — but how the practitioner develops perception capable of encountering that presence. The Me'or Einayim returns, in every parasha, to the same essential move: whatever the Torah text is describing, it is describing the state of divine light in relation to its vessels.
This was not allegorism. Nachum did not treat the biblical stories as codes for something else. He treated them as literal accounts of how divine light moves through the world — accounts that remain accurate because the dynamics they describe are the eternal dynamics of the real. The Exodus is happening now; Sinai is accessible now; the Promised Land is the state of consciousness in which divine light is perceived everywhere.
The Inner World
Nachum placed unusual emphasis on the inner world of thought as the primary site of spiritual practice. External acts — prayer, commandment-observance, Torah study — were indispensable, but their value depended on the quality of consciousness within which they were performed. A Torah learning session conducted in distraction was far inferior, in his view, to a moment of simple awareness saturated with devekut (divine cleaving).
This created a distinctive pastoral posture. He did not demand of his community elaborate Kabbalistic practices or intensive study regimes. He asked them to be present: to notice what they were thinking, to bring their awareness to the divine in ordinary moments, to let the quality of their attention be the measure of their service. In this, he stood closer to the Baal Shem Tov's populist accessibility than to the intellectualism that would characterize the Chabad line.
Tikkun of the Inner Life
One of the Me'or Einayim's most psychologically nuanced teachings concerns what to do with unwanted thoughts — the distractions, temptations, and shadows that arise during prayer and study. The standard approach, inherited from earlier ascetic traditions, was to suppress or reject them. Nachum taught the opposite: every fallen thought contains a divine spark in exile, and the correct response is elevation rather than rejection.
The mechanism is recognition: when a distracting thought arises, the practitioner identifies the spark within it (What is this thought really reaching for? What legitimate need or perception is distorted here?), draws that spark upward into conscious awareness, and releases the distorted vessel. This is not permission to indulge every distraction — it is a sophisticated practice of transformation. The thought is not pushed away; it is metabolized. The sparks imprisoned within the fallen thought are freed, and the thought itself dissolves.
Reflecting the Light
Nachum's version of the Tzaddik doctrine — while less structurally elaborate than Elimelech's — has its own precision. Where Elimelech conceived the Tzaddik as cosmic intermediary and channel of divine abundance, Nachum conceived the Tzaddik primarily as a mirror of the divine light: one who has so thoroughly cleared the obstructions from their own consciousness that what shines from them is not their own light but God's light, reflected back to those who stand before them.
The implication was both humbling and demanding. The Tzaddik has no light of his own — he is transparent. His task is to prevent his personality, desires, and ego-structures from filtering or distorting what passes through him. The community's devotion to the Tzaddik is not, ultimately, devotion to him: it is their recognition that this particular lens offers a clear view of what they have been seeking all along.
Simcha and Perception
Nachum inherits the Baal Shem Tov's emphasis on simcha (joy) but gives it an epistemological grounding that the founder had left implicit. For Nachum, joy is not merely a mood state or a religious obligation — it is a precondition for perception. A consciousness contracted by depression, anxiety, or grief cannot see the divine light that is always present. The walls of the contracted self block the light the way dense stone blocks sunlight.
Cultivating joy is therefore not self-indulgence but spiritual preparation: the expansion of consciousness necessary for the perceptual faculty to operate. When Nachum prescribes joy — and he does, consistently, as one of the most important acts of divine service — he is prescribing not a feeling but a state of openness, an expansion of the inner vessel that makes reception of divine light possible. Depression is not merely unhappiness; it is a form of blindness, a closing of the eyes through which the divine would otherwise be seen.

The Life in Depth
The Baal Shem Tov's Teaching on Immanence — Received at the Source
Nachum came to the Baal Shem Tov during the Besht's mature teaching years — a period when the founder was at the height of his transmission. What Nachum received there was not primarily doctrine but a quality of perception: the ability to see divine light in what others saw as ordinary matter. The Besht taught this not through systematic exposition but through the texture of his presence and through targeted teachings that broke open the conventional split between sacred and mundane.
One teaching Nachum absorbed and returned to throughout his life: the verse "the whole earth is full of His glory" (Isaiah 6:3) is not poetry or metaphor — it is a literal description of the situation. If God's glory fills the earth, then everything in the earth is the glory of God in some specific form. The task is not to seek the divine elsewhere but to learn to see what is already everywhere present.
The Besht also gave Nachum what might be called the permission of immanentism: the permission to find God in unexpected places, in the coarse and the base as much as in the refined and the elevated. Where the earlier Kabbalistic tradition — following the Lurianic system of worlds and hierarchies — tended to locate the divine most intensely in the higher worlds and most dimly in the lowest material levels, the Besht pushed against this hierarchy. The divine sparks (nitzotzot) are precisely most in need of elevation in the lowest places — which means the lowest places are, in a certain sense, where the most intense divine presence is currently hiding.
Nachum made this the central burden of his teaching career: the divine is not more present in the synagogue than in the marketplace. It is not more accessible in prayer than in honest business dealing. The one who brings awareness of God's presence into every act — however mundane — is performing the most radical spiritual work. This is what the Besht had taught. This is what the Me'or Einayim would systematically demonstrate through hundreds of pages of Torah commentary.
Chernobyl — Building a Dynasty
When Nachum settled in Chernobyl, he inherited the model of the Hasidic court that had been established by the Maggid's generation: the Rebbe as communal center, teacher, intercessor, and channel of divine blessing. But he shaped this model with his own emphasis. His court was known less for the elaborate structure of the Tzaddik doctrine (which was Elimelech's domain) and more for the quality of its atmosphere — a quality of warmth, of divine presence felt in the air of the Rebbe's room, of joy that was not forced but arose naturally from the conviction that God was there.
His teaching practice was primarily oral. The Me'or Einayim was compiled by his students from his spoken discourses — the drashas he gave on Shabbat and holidays, woven around the week's Torah portion. This oral character is preserved in the text's style: it reads as spoken teaching, with the back-and-forth of question and resolution, the sudden turns of insight, the repetition of key phrases that marks a teaching meant to be heard and absorbed rather than parsed analytically.
His eight grandsons — Mordechai's sons — each became Rebbes in different towns: Trisk, Skvira, Talnoye, Rachmistrivka, and others. This geographic dispersal was not accidental. The Hasidic dynasty's strength depended on its ability to maintain connection to a central transmission while planting roots in local communities. Each of Mordechai's sons carried the Chernobyl light into a different terrain and adapted it to local conditions, while the connection back to the grandfather's teaching held the whole constellation together.
The Twersky family's dynasty remains one of the most numerically extensive in the Hasidic world. The Skverer Rebbe, based today in New Square, New York — a village the dynasty built — is among the most prominent. The Talner Rebbe in Boston carries another branch. Each traces its lineage directly back to the man who first sat in Chernobyl and saw, in the small Ukrainian town's ordinary life, the light of the Infinite shining without concealment for those who had eyes to see it.
The Me'or Einayim — A Topology of Light
The text published posthumously in 1798 under the title Me'or Einayim is organized as a weekly Torah commentary — each section keyed to a parasha of the annual reading cycle. But its actual structure is thematic: the same concerns reappear, across different biblical contexts, with new facets exposed by each new application. Reading it linearly (as Torah commentary) and reading it thematically (as a meditation on light, perception, and the divine presence) are both valid approaches; the text rewards both.
Its most distinctive structural feature is what might be called its topology of light: the careful mapping of how divine light moves through different conditions — revealed and concealed, manifest and withdrawn, ascending and descending. Every element of the Kabbalistic world-picture is reread as a description of light-dynamics. The Tzimtzum (divine contraction) is the moment at which the Infinite steps back not to absent itself but to create the space within which a finite light can be perceived — within which the Infinite can be encountered in terms that finite beings can receive.
The Me'or Einayim also contains some of the most nuanced treatments of the relationship between mochin d'gadlut (expanded consciousness) and mochin d'katnut (contracted consciousness) in early Hasidic literature. These terms — borrowed from Lurianic Kabbalah — describe the oscillation of the practitioner's inner state between periods of expanded divine perception and periods of contraction, in which the light seems to withdraw and ordinary consciousness resumes. Nachum normalizes this oscillation: it is not a failure to maintain the expanded state, but the rhythm of spiritual life as it necessarily unfolds within time. The contraction is not absence of the divine but the divine in a different mode — present even in the moments of hiding, available even when unseen.
This teaching is connected to the broader doctrine of ratzo u'shov — the running and returning of divine energy — which appears throughout Hasidic thought. Nachum develops it in a particularly compassionate direction: the practitioner who finds themselves in a state of contraction is not failing. They are participating in the same rhythm that characterizes divine reality itself. The skill is not to prevent the contraction but to recognize it for what it is, and to wait — in simple, faithful awareness — for the light to return.
