Yichudim
Isaac Luria, the father of modern Kabbalah, developed the Zoharic references to Yichudim into a complete esoteric system of meditation, based on the new mythological scheme of Lurianic Kabbalah. Outwardly, the Zohar appears to be solely a theosophical text. However, through Luria's theosophical description of the cosmic structure as a complete interacting dynamic system, the soul of man embodies and dynamically interacts with the supernal processes of creation. Where Moses Cordovero previously developed a linear Zoharic method of meditation based on his conception of the sephirot as discreet powers, Luria's Yichudim meditation method is based on the sephirot as anthropomorphic mutually enclothing Partzufim (divine personas). His systemisation of Zoharic doctrine into a comprehensive process, enabled him to extract Yichudim meditation practices from the most esoteric descriptions in the Zohar. These elite meditative practices engaged the attention of subsequent Kabbalistic worship, and were further expanded, and practiced in a communal setting by Shalom Sharabi and the Beit El circle.
