Or HaGanuz LaTzaddikim – Teachings of the Baal HaTanya – Zhovkva, 1800 – First Edition
Or HaGanuz LaTzaddikim, "compiled from books and from the teachings of holy sages… explaining Chassidic conduct and desirable character traits, which are described in all the books of Tzaddikim…", by R. Aharon HaKohen of Apta. Zhovkva, 1800. First edition, with the approbation of the Maggid of Kozhnitz.
The book was published about four years after the printing of the Tanya by Rebbe Shneur Zalman of Liadi. The author, a prominent Chassidic Tzaddik, bases many of the thoughts in his book on the teachings of the Tanya, which he quotes and elaborates upon in almost every Torah portion.
R. Aharon HaKohen of Zelichov (Żelechów) and Apta (Opatów; Encyclopedia L'Chassidut, I, p. 157), author of Keter Shem Tov – the renowned compendium of the Baal Shem Tov's teachings, and of the Tefilla Yeshara – Keter Nehora siddur. His book Or HaGanuz LaTzaddikim was first published anonymously.
