הרב יעקב יצחק רבינוביץ

Yaakov Yitzchak Rabinowicz of Peshischa also known as the Yid Hakudosh or the Yehudi was the founder and first Grand Rabbi of the Peshischa movement of Hasidic philosophy, and an important figure of Polish Hasidism. The leading disciple of Yaakov Yitzchak of Lublin, the Yehudi preached an "elitist" approach to Hasidism, in which he paired traditional Talmudic learning with the highly spiritual Kavanah of Hasidism. He encouraged individuality of thought, which brought his movement into conflict with the Hasidic establishment. Nevertheless, several of his teachings would go on to influence large percentages of modern Hasidism. Following his death in 1813, he was succeeded by his main disciple Simcha Bunim of Peshischa, who increased his movement's influence tenfold. The Yehudi is the patriarch of the Porisov and Biala Hasidic dynasties.
