Or LaShamayim, Chassidic essays on the Torah portions, novellae on Talmudic topics and responsa, by Rebbe Meir HaLevi Rotenberg Rabbi of Stovnitz and Apta, disciple of the Chozeh of Lublin. [Lviv: printer not indicated, 1850]. First edition. Approbation by the Divrei Chaim of Sanz at the end of the book.
The author's famous prayer is printed at the beginning of the book: "Ribbon HaOlamim Yodati Ki Hineni BeYodcha..." ("Master of the Universe, I know that I am in your hands like clay in the hands of a potter..."). Later editions of the book, starting from the 1914 edition, state that the Tiferet Shlomo of Radomsk would recite the prayer twice daily, and declared that reciting the prayer daily is an awesome segulah for livelihood and success.
The book was compiled and brought to print by the author's son-in-law, R. Menachem Mendel Rubin Rabbi of Głogów, who describes in his foreword how when the author spoke, it was as if the Divine presence was speaking from the author's mouth, and all his teachings were Heavenly revelations he received at that time.
On the title page and on several other pages, signatures (in pencil) and stamps of Rebbe Mordechai David Teitelbaum of Safed.
