Shimon Chyrek

Magid Shiur

Collaborated with and contributed to the following projects and institutions

Our journey to Poseach Shaar

In 2018, the Magid Shiur, Rabbi Shimon Chyrek, led an intensive training in Tanya fundamentals for the staff of Chayolei Tzivos Hashem.
The intent was clear: sharpen missions, improve “to-do” checklists for the youth, and align publications and services with those goals. The feedback we heard most was a request for something to do every day—a steady way to reinforce what was learned in the training.

From that feedback, a next step emerged: Prayer Principles — ליקוט הכנה לתפילה, prepared to the standards of Kehot and published in 2020. It’s available in the Kehot store and on Amazon.
“The Kehot Logo is a registered trademark of Merkos L’inyonei Chinuch.”

Before the above, Rabbi Chyrek coordinated Dach Yomi—an acronym for דברי אלקים חיים (Divrei Elokim Chaim)—with the vision to complete the entire Torah Or and Likkutei Torah of the Alter Rebbe in about five years by learning a single column each day. To support comprehension, Rabbi Levi Gelb’s commentary was added to much of the Dach Yomi publication. Because Torah Or and Likkutei Torah are to Pnimius HaTorah what Shas is to Nigleh, the name Dach Yomi—echoing Daf Yomi—fits naturally.

Another cornerstone was accessibility—to strengthening trust in Hashem. The Magid Shiur engaged a professional voice artist to record Shaar HaBitachon (Gate of Trust) from Chovas HaLevavos in clear English. In about four hours, a listener can complete the entire Shaar HaBitachon and return to it again and again; this audio is available on Amazon. With this recording experience, he also coordinated the audio version of the Tzivos Hashem study guides for the Chidon Sefer HaMitzvos of the Rambam..

Why trust matters so much for Tefillah and Poseach Shaar: After the Avoda of Tefillah, the next stage is Simcha and Bitachon—trust that Hashem will make the Avoda effective (Likkutei Dibburim, vol. 3, p. 460). That progression sits at the heart of our approach.

All of this experience now converges in Poseach Shaar.
The training, the daily discipline, the video and audio shiurim are being brought together so participants can open the gate—building a living relationship with Hashem through structured learning, practiced trust, and heartfelt tefillah and building a rich vocabulary to communicate Chassidus.

Is this for me?

Why choose us

Join a living movement in Chassidus learning

Real-world standard: what this looks like in Israel

In Eretz Yisroel, a Chassidus Kollel completed a rigorous year of Shaar HaYichud—with weekly shiurim, monthly tests, and formal certification for those who mastered the material. This is the level of seriousness we align with. When you join Poseach Shaar as a Chaver, you commit to the same baseline of depth, clarity, and accountability—delivered in English with our guidance and structure.

Source: Tanya, Kuntres Acharon 4 — cites Deut. 4:39 & 1 Chron. 28:9

שידיעת המציאות מההשתלשלות היא ג״כ מצוה רבה ונשאה, ואדרבה עולה על כולנה, כמ״ש וידעת היום כו׳, דע את אלקי אביך כו׳, ומביאה ללב שלם.

“that the knowledge of the metziut (that-ness) derived from the order of hishtalshelut is likewise a great and exalted mitzvah,” i.e., clearly grasping that these spiritual levels must exist and how they relate—even if we do not claim their inner mahut, “and moreover, it surpasses them all,” because such disciplined knowledge aligns a person’s inner “program”—mind, emotions, and will—with the Divine order, “as it is written, ‘And you shall know today’ (Deut. 4:39) and ‘Know the G-d of your father’ (1 Chr. 28:9),” verses that call not just for belief but for worked-through knowledge, “and it brings to a whole heart (lev shalem).” By aligning our inner program to that order, we arrive at an undivided heart in service.

Clear guidance from the Rebbeim on learning Shaar HaYichud first—so your learning is ordered, testable, and part of a living mesorah.

אמאהל פלעגט מען ניט אראיינגלאזן יונגע צו חסידות, מען האט פריער גידארפט וויסן לכל הפחות דעם סדר ההשתלשלות, דיא סטאנציעס — וואס דאס איז דער ספר שער היחוד פון דעם מיטעלער רבין.

English: In earlier times, young people were not admitted to Chassidus until they knew at least Seder Hishtalshelus—the basic “stations” of the path—which is precisely what the Mitteler Rebbe’s Shaar HaYichud teaches.

Program note: the Rebbeim wanted Chassidus learned with the rigor of Nigleh—clear and accountable progress. Like a semicha track motivates effort, Poseach Shaar tests the “stations” of Seder Hishtalshelus.

Mitzvah & obligation (Rebbe Maharash)

“Who can know Seder Hishtalshelus and doesn’t—[is lacking]. Knowing it is a mitzvah and an obligation.”

Source (Hebrew / English)

Source: Sefer HaToldos (Rebbe Maharash), p. 81 — said at the beginning of the year 5632 (1871)

בראשית שנת תרל״ב אמר הרבי מהר״ש: דער וואס איז שייך צו וויסן סדר ההשתלשלות ואינו יודע — איז נישט בסוג מדבר. ווייל יעדער צייט דארף מען וויסן וואו די נשמה איז. ידיעת סדר ההשתלשלות איז מצוה וחובה!

English: At the beginning of the year 5632, the Rebbe Maharash said: “One who is capable of understanding Seder Hishtalshelus and does not — is not in the category of Medaber (a fully realized human). For at all times one must know where the soul is. Knowledge of Seder Hishtalshelus is a mitzvah and an obligation!”

Knowing the map is part of being who we’re meant to be.

Order first (Rebbe Rayatz → from his father)

“Chassidus must be learned in order—the first thing is to know Seder Hishtalshelus… the main thing is the order.”

Source (Hebrew / English)

Source: Igros Kodesh (Rayatz), vol. 3, p. 104

פעם — מספר כ״ק אדמו״ר הריי״צ: כשנכנסתי ליחידות ושאלתיו בענין חסידות, השיב לי בקצרה: חסידות דארף מען לערנען מיט אַ סדר — דאס הייסט, די ערשטע זאַך איז ידיעת סדר ההשתלשלות, ווי דער זיידע (אדמו״ר האמצעי) שרייבט אין שער היחוד. און תיכף זאגט דער טאטע: חסידות איז נעוץ תחלתן בסופן וסופן בתחלתן, אבער דער עיקר איז סדר.

English: The Rebbe Rayatz related: When I asked my father in yechidus about Chassidus, he answered briefly: “Chassidus must be learned in order—that is, step by step—the first thing is to know Seder Hishtalshelus, as the Zeide (the Mitteler Rebbe) writes in Shaar HaYichud. And immediately he would add: ‘Chassidus is bound end in beginning and beginning in end,’ the circle is complete, but the main thing is the order.”

Structure first; then you appreciate the full circle.

Key & Alph-beis (HaYom Yom Shushan Purim)

“Shaar HaYichud is the key to Chassidus; Shaarei Orah is the alphabet.”

אאזמו״ר אמר: אדמו״ר האמצעי כתב עבור כל סוג וסוג של המשכילים והעובדים, מאמרים וספר מיוחד, לבד שער היחוד ושערי אורה שהם כלליים. שער היחוד הוא המפתח לתורת החסידות, ושערי אורה — האל״ף־בי״ת של תורת החסידות.

English: My grandfather said: The Mitteler Rebbe wrote a specific sefer or maamar for every type of maskilim and ovdim—tailored pathways for different minds and temperaments—except for Shaar HaYichud and Shaarei Orah, which are general works. Shaar HaYichud is the key to Chassidus; Shaarei Orah is the alphabet of Chassidus.

One is the master key; the other is the alef-beis—the basic letters from which everything is spelled.

Detailed knowledge required (The Rebbe)

“One must have detailed knowledge of Seder Hishtalshelus—and of the details of Tzimtzum.”

Source (Hebrew / English)

Source: Basi LeGani 5745 (1985) — citing the Mitteler Rebbe’s Shaar HaYichud

מבאר כ״ק אדמו״ר האמצעי בשער היחוד שלו: שצריך להיות ידיעה בפרטיות של סדר ההשתלשלות, וגם בפרטי ענין הצמצום וכּו׳.

English: The Mitteler Rebbe explains in Shaar HaYichud: one must have detailed knowledge of Seder Hishtalshelus, and also of the particulars of Tzimtzum, etc. That is, real progress requires clarity in the structure and its fine points—not just generalities.

Depth lives in the details.

Thorough & accessible (The Rebbe)

“Chabad’s approach is to understand matters thoroughly, in a style graspable even to the animal soul… I have seen no true beginning in this—aside from the Mitteler Rebbe’s Shaar HaYichud (brief).”

Source (Hebrew / English)

Source: Igros Kodesh, vol. 27, p. 133

… ומתאים לשיטת חסידות חב״ד שאחת הנקודות העיקריות בזה להבין הענינים על בורים, ובסגנון הידוע שיהי׳ מובן גם בשכל נפה״ב, הנה לא ראיתי אף התחלה בזה, מלבד שער היחוד לאדמו״ר האמצעי שהוא ע״ס ההשתלשלות, אבל בקיצור נמרץ. …

English: And this fits the approach of Chabad Chassidus, that one of the principal points is to understand matters thoroughly, presented in the well-known style so that even the nefesh ha-behamit (“animal soul”) can comprehend; yet I have not seen even a beginning in this direction—a true, systematic opening—aside from the Mitteler Rebbe’s Shaar HaYichud, which addresses Seder Hishtalshelus, but only very briefly.

Thorough understanding—accessible to every mind.

Gateway to Chassidus (Toldos Maharash)

“Beyond mapping Seder Hishtalshelus, Shaar HaYichud opens a gateway to comprehension of Chassidus itself.”

Source (Hebrew / English)

Source: Sefer HaToldos (Rebbe Maharash), Addendum 2, p. 66

שער היחוד, לבד מהשכלה של ידיעת סדר ההשתלשלות אשר בו, הנהו פותח שער בהשכלה של חסידות.

English: Aside from the understanding of Seder Hishtalshelus contained in it, Shaar HaYichud opens a gateway to the comprehension of Chassidus itself.

Not just the map— the gateway to Chassidus.

About the Program

What is Poseach Shaar?

Poseach Shaar has two simultaneous lanes:

  1. A structured program that helps you live Tanya by practicing the Alter Rebbe’s 16 motivational activities in an organized, simple way—with just a few minutes in the morning and evening.

  2. The study of Seder Hishtalshelus, where learning the definitions of Chassidus terminology opens the gate to deeper comprehension in the study of Chassidus.

Both lanes complete each other: one grounds you in avodah, the other opens your mind to understanding. Together, they open a gateway—פותח שער—to living and learning Chassidus.

Only about 4 minutes at night before Krias Shema and 8 minutes in the morning before davening. That’s all it takes to practice the Alter Rebbe’s 16 motivational activities. The impact comes from steady consistency, not long hours—and all you need is a Tanya in print.

In addition, there are two evening classes each week on Zoom. The schedule is printed in the syllabus, and if you can’t attend live, you’ll get access to the class recording so you never miss out.

Alongside this, you’ll verbally review each chapter of the Mitteler Rebbe’s Shaar HaYichud a few times during the week. This simple practice isn’t heavy—it’s what allows the ideas to become clearer, more natural, and alive. Each review deepens your connection and makes the learning part of you.

The daily Tanya readings give you simple, repeatable tools for inspiration. The study of Seder Hishtalshelus with the words of the Mitteler Rebbe ensures that these core practices never become repetitive, but gain deeper meaning as you progress.

Practical Concerns

Ask yourself: When you said Elokai Neshama this morning, did you have the kavana described in Chapter 41 of Tanya? Most of us do some practices, but not systematically. If you want the full impact of the Alter Rebbe’s guidance, this course is for you.

That’s wonderful—but the Alter Rebbe’s intent is achieved through the cumulative impact of many small practices done together. Poseach Shaar helps you integrate all 16 activities into a daily rhythm so you can experience that full effect.

No—the program is designed for active participation. By verbally reviewing the chapters of Shaar HaYichud multiple times, the ideas become second nature and truly internalized. This is also how Tanya’s vision of “כי קרוב אליך” comes alive.

Authenticity

No. Many of these practices are already familiar in Chabad life, such as reading from Tanya before davening. Poseach Shaar simply organizes what’s already there and makes it systematic, so you can experience their full impact.

Not at all. We always return to the actual words of the Alter Rebbe, reading directly from a Tanya. Nothing is added or altered—only structured for daily use, exactly as intended.

On the contrary. The daily Tanya passages become richer when paired with the broader study of Seder Hishtalshelus. Together, they connect the klalim (principles) with the pratim (details), making each reading fresh and meaningful.

Identity & Commitment

Joining Poseach Shaar means committing to systematically practice Tanya. A chaver is someone who has “bought in” (קנה לך חבר)—not just by paying for a course, but by joining a community of fellow learners who support one another in farbrengens and growth.

You’ll gain accessible daily inspiration, deeper kavana in tefillah, and clarity in learning Chassidus. Instead of scattered efforts, you’ll have an organized path that saves time while ensuring long-term growth and competence.

Is this for me?

Melamed / Teacher (מלמד) – Turn sound bites into a system

You do Chinuch every day—but sometimes it can feel like sound bites.

  • Unify the parts: See the “engine of Yiddishkeit” as an integrated system—know which component to strengthen.
  • From Nigleh to Pnimiyus: Apply the derech halimud to learn inner Torah with clarity of Nigleh.
  • Model growth: Even if you’re not teaching Seder Hishtalshelus, your talmidim see your ongoing growth.

Ready to open the gate for your classroom?

Community Rabbi / Shliach – Hafatzas HaMayanos with tools
  • Fluency in Tanya & Shaar HaYichud: Speak Pnimius HaTorah with clear terminology (keilim d’tikun).

Strengthen your hora’ah

Maggid Shiur – Captivate with clarity
  • More ways to explain: A shared conceptual language with multiple metaphors for complex sugyos in Chassidus.

Therapists, Coaches & Social Workers – Torah-first frameworks
  • Foundations first: Anchor methods in Torah’s model of the nefesh and avodah.
  • Integrate wisely: Engage secular tools from a place of clarity, not replacement.
  • Guide toward wholeness: Sometimes the “issue” is a soul’s longing for avodah.

Build on Torah clarity

Parents & Grandparents – Model lived Chassidishkeit
  • From ideas to middos: As the Rebbe Rashab taught—Chassidus is for middos transformation.
  • Lead by example: Show lifelong growth and refined hanhagos at home.
  • Shared language: Speak about mitzvos and avodah with clarity and simchah.

Inspire your family

Practical Concerns

Do I need prerequisites before joining?
  • Tanya: You’ve gone through Likkutei Amarim (we don’t cover its basics in class).
  • Dinim & Gemara: Prior experience—our derech halimud draws from Nigleh to learn Pnimius.
  • Chassidus: The more the better; minimum = Tanya.
  • Hebrew: Reading ability only; we translate everything into English.
These prerequisites make sure class time is used for depth, not basics.
