What is the Great Work?

"Do not pray for your own needs, for your prayer will not then be accepted. But when you want to pray, do so for the heaviness of the Head. For whatever you lack, the Divine Presence also lacks."

"This is because man is a "portion of God from on high." Whatever any part lacks, also exists in the Whole, and the Whole feels the lack of the part, You should therefore pray for the needs of the Whole."

The term "the Great Work" has many definitions, and is not a term from traditional Kabbalah, but it has a modern usage among some Kabbalists. The quotation above, from a disciple of the Kabbalist R. Israel Baal Shem Tov, is a traditional Kabbalistic view: that the creation is in a damaged and imperfect state, and the Kabbalist, by virtue of his or her state of consciousness, can bring about a real healing. A name for this is "tikkun" (restoration). There are many traditional forms of tikkun, most of them prescriptions for essentially magical acts designed to bring about a healing in the creation.

This view of the Great Work also exists outside of Judaic Kabbalah and survives today, namely that the creation is in a "fallen" state, and each person has an individual role to play in bringing about a general restoration.

"When someone stands in the light but does not give it out, then a shadow is created."

This is a modern restatement of an old Kabbalistic idea. In this view, God gives life to the Creation: from second to second the Creation is sustained by this giving, and if it were to cease even for an instant, the Creation would be no more. If someone wants to know God then they have to resemble God, and this means they must give to others. Kabbalah is not a self-centred pursuit; it pivots around the Kabbalist's relationship with all living beings.
