(Gaon of Vilna). Tikunei HaZohar, with: Tikunim from Zohar Chadash. With commentary Biur HaGr”a by the Vilna Gaon.

Published by the philanthropist Shmarya Zuckerman (the Gaon was Mrs. Zuckerman’s great-grandfather) who collected and published many of the Gaon’s writings. It is particularly noteworthy as it was published from the Gaon’s autograph manuscript as opposed to notes recorded by students. The introduction records the comment by R. Abraham, the son of the Gr”a, noting that his father wrote thirty works on the Zohar and he would not be ashamed to recite them to R. Shimon B”r Yochai himself! It is a custom among many communities to study portions of this work daily, especially during the month of Elul through Yom Kippur. See the forty day calendar at the end of the introduction.
