Rabbi Aharon Rokeach, known throughout the Torah world with trembling awe as "Der Heiliger Belzer Rebbe" (The Holy Belzer Rebbe), was one of the most angelic, hidden, and miraculous leaders in the history of Chassidus.

As the fourth Rebbe of the magnificent Belz dynasty, his life was split into two distinct, world-shaping eras: serving as the sovereign ruler of hundreds of thousands of European Chassidim before the Holocaust, and single-handedly rebuilding his shattered kingdom from the ashes in Eretz Yisrael after losing everything.

1. Otherworldly Kedushah and Prishus

Even among the greatest tzadikim, the Holy Belzer Rebbe was spoken of as a being who walked this physical earth but belonged entirely to the upper spiritual worlds. He lived a life of radical Prishus (abstinence) and absolute Kedushah (holiness).

• Guarding the Eyes: From his youth, the Rebbe guarded his sight with supernatural intensity. He walked with his eyes cast down and never looked at the face of a woman, nor did he even look directly at the faces of his own children or closest attendants. When speaking to people, his gaze was turned elsewhere.

• Asceticism: He barely ate enough to sustain human life, fasting for days on end and taking only microscopic bites of food at his tish (communal table). His holy hands were wrapped in towels or tissues at all times to maintain the highest levels of halakhic purity.

• The Power of His Brachos: He was universally regarded as a Poel Yeshuos—a worker of open salvation and miracles. Thousands of Chassidim, Litvishe Jews, and Sephardic sages streamed to his court in Galicia, Poland, because it was an accepted fact that whatever the Rebbe decreed down on earth, Hashem fulfilled in Heaven.

2. Through the Fire of the Holocaust

Before World War II, Belz was a global citadel of Torah. When the Nazi beast $y''s$ invaded Poland, the Gestapo explicitly marked the Belzer Rebbe as a prime target, desperately seeking to capture the spiritual heart of Galician Jewry.

The Rebbe was hidden by devoted Chassidim and smuggled from ghetto to ghetto (including Bochnia and Przemyślany) in heart-stopping, dangerous escapes. Tragically, the suffering born by his household was unimaginable: the Rebbe’s wife, his children, his grandchildren, and his entire extended family were systematically murdered by the Nazis.

In 1943, wrapped in a string of open miracles, the Rebbe and his holy brother, the Bilgorayer Rav (Rabbi Mordechai Rokeach), were disguised as Polish drivers and smuggled across the border into Hungary, eventually arriving in the safe haven of Eretz Yisrael in 1944.

3. Rebuilding the Kingdom from the Ashes

When the Holy Belzer Rebbe stepped onto the soil of Tel Aviv, he was physically broken, emaciated, and completely alone—stripped of his family and his hundreds of thousands of followers.

Where an ordinary human being would have broken down from grief, the Rebbe displayed a divine resilience. He looked at the few broken, traumatized survivors who gathered around him and laid down a fundamental rule of mussar:

He immediately set out to resurrect the name and spirit of Belz. He settled in Tel Aviv and later established the center of the Chassidus in Yerushalayim. Because his brother, the Bilgorayer Rav, passed away in 1949, the Rebbe took his brother’s young orphaned son—the current Belzer Rebbe, Rabbi Yissachar Dov Rokeach—under his direct, grandfatherly wing, training and grooming him from early childhood to ensure the golden chain of the dynasty would never be severed.

4. His Tziyun (Tomb) on Har HaMenuchot

The Holy Belzer Rebbe passed away on the 21st of Av, 5717 (1957). His levaya (funeral) was one of the largest and most solemn in the history of Yerushalayim.

Unlike his three predecessor Rebbes who were buried in the old cemetery of Belz (in modern-day Ukraine), Rav Aharon was the first to be buried in the holy soil of Har HaMenuchot in Yerushalayim.

A Fortress of Salvation

Today, his tomb (Ohel) is one of the most frequented sites of pilgrimage in all of Israel.

• The Power of a Sufferer: It is an accepted Torah principle that a tzadik who endured the ultimate depths of human suffering while remaining completely pure possesses immense power to act as a Melitz Yosher(righteous advocate) for us in Heaven.

• Daily Prayers: At any hour of the day or night, the Ohel is packed with Jews from all walks of life—Chassidim, Litvaks, and Sephardim—weeping over Tehillim (Psalms), lighting candles, and leaving Kvitlach (written prayer petitions) on his gravestone, seeking yeshuos for health, livelihood, and children.

• The Yahrzeit: Every year on the 21st of Av, tens of thousands of Jews make the trek up Har HaMenuchot. The current Belzer Rebbe leads a massive gathering at the site, pouring out his heart for the collective welfare of Clal Yisrael.

In the frum world, Rabbi Aharon of Belz is remembered as the ultimate symbol of Jewish eternity: the holy master who looked directly into the face of absolute darkness, refused to let the fire of Chassidus die, and through pure faith, planted the seeds for the miraculous resurrection of the Torah world we see today. May his holy memory and zechut shield us all.
