138 Openings of Wisdom makes available online the first English translation of KLaCh Pischey Chokhmah by the outstanding kabbalistic genius, Rabbi Moshe Chaim Luzzatto ("RaMChaL", 1707-47). The translation is an ongoing project by Rabbi Avraham Greenbaum. New sections are being posted as they become available.
138 Openings of Wisdom was written by Ramchal as the final step on a ladder of initiation into the kabbalistic wisdom that starts with Derekh HaShem ("The Way of G-d") and Da'as Tevunos ("The Knowing Heart"). Those embarking on the study of Kabbalah are advised to study these works first.
138 Openings of Wisdom is considered by leading scholars to be the classic exposition of the kabbalistic system, providing the student with all the concepts and understandings necessary in order to navigate and find meaning in the Zohar, the writings of the ARI and other kabbalistic literature.
