Son of Rabbi Alexander Sender, who was the founder of the Komarna dynasty. Orphaned at a young age, Yitzchak Aizik was raised by his uncle, Rabbi Tzvi Hersh of Zhidichoiv. He authored many important Chassidic and Kabbalistic works, frequently quoting the Baal Shem Tov, of whom he considered himself a disciple although he was born after the latter's death. Among his better-known works are "Heichal HaBeracha" on Torah, "Zohar Chai" on the Zohar, and "Shulchan HaTahor" on Shulchan Aruch. A diary in which he recorded supernatural visions he experienced, the existence of which was originally known only to select individuals, has recently been published from manuscripts under the title "Megilat Setarim."
