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.
Example of Lurianic Yichudim meditation In the same way that the Lurianic
partzufim interact and enclothe within each other, so in Lurianic Yichudim meditations these supernal processes are theurgically enacted in the psyche by combining, and usually enclothing the letters of particular divine names within each other. A simple Yichud meditation example: "The lower soul (nefesh) is from the Universe of
Assiah, which is associated with the name Adonay ("Lord" the divine name associated with the Sefirah
Malkuth). One should therefore meditate on the name Adony (ADNY) binding it to the name YHVH (
Tetragrammaton name associated with the Sefirah
Tiferet) in the Universe of Assiah. He should then bind this to the name Ehyeh (AHYH "I Am" associated with the Sefirah
Keter) in the Universe of Assiah.He should then meditate on this, elevating the name Ehyeh of Assiah, and binding it to Adonay of
Yetzirah. Adonay of Yetzirah should then be bound to YHVH of Yetzirah.One proceeds in this manner step by step, until he reaches Ehyeh of
Atziluth. He should then bind Ehyeh of Atzilut to the very highest level, which is the Ein Sof." Luria instructs many detailed and advanced Yichudim meditations for particular purposes. As well as
Kavanot for prayer and to accompany Jewish observances, these include meditations enacted while prostrated on the grave of a saint, a practice of the 16th century
Safed Kabbalists in order to commune with the righteous soul. == Kavanot of prayer in Hasidism ==
