Emek ha-Melech (Valley of the King), published by Rabbi Naftali Tzvi Bacharach in Amsterdam in 1648, represents the Israel Sarug school of Lurianic transmission, an alternative system directly in dialogue with Etz Chayyim. Never before translated into English. Bacharach synthesizes the complex teachings scattered throughout the Lurianic corpus, organizing them into a coherent system with extensive commentary. This translation includes the complete text with annotations identifying Bacharach's sources and explaining his interpretive choices. The complete three-volume English edition is now available.
