Machon Rabbi Chaim Vital is an independent scholarly institute established by Rabbi Aharon Samekhov, dedicated to the preservation, study, and publication of the Torah teachings and writings of Rav Chaim Vital ז״ל, the foremost disciple and principal transmitter of the teachings of the Arizal.

​

The work of the Machon is grounded in careful manuscript research, historical responsibility, and fidelity to the earliest and most reliable sources. Over many years, manuscript witnesses of Rav Chaim Vital’s writings have been located from collections around the world, systematically compared, and critically organized in preparation for accurate publication.

​

Our guiding principle is to present these texts in accordance with the manner in which they were transmitted and recorded in the original sources, without conjecture, embellishment, or later editorial interpolation. The goal is not reinterpretation or innovation, but responsible preservation and clear presentation of the received tradition.

​

This project is conducted as an independent scholarly initiative and is not affiliated with any other publisher or institution.

​

Our most recent project: Siddur of Rabbi Chaim Vital

​

Our most recent publication is Siddur of Rabbi Chaim Vital, a manuscript-based presentation of what has come to be known as Nusach HaAri.

This siddur is compiled from the prayer rite practiced by the Arizal and Rabbi Chaim Vital himself and includes the relevant halachot, minhagim, teachings, and yichudim, drawn directly from the original writings of Rabbi Chaim Vital.

The siddur reflects a careful synthesis of textual fidelity, halachic precision, and clarity, intended for serious students of tefillah and Kabbalah.
