The nodes are usually represented as spheres and the lines are usually represented as paths.[1] The nodes usually represent encompassing aspects of existence, God, or the human psyche.[2][3][4] The lines usually represent the relationship between the concepts ascribed to the spheres or a symbolic description of the requirements to go from one sphere to another.[2][4] The nodes are also associated to deities, angels, celestial bodies, values, single colors or combinations of them, and specific numbers.[3][5] The columns are usually symbolized as pillars.[2] These pillars usually represent different kinds of values, electric charges, or types of ceremonial magic.[2][5] It is usually referred to as the Kabbalistic tree of life in order to distinguish it from other concepts with the same name.[5][6] In the Jewish Kabbalah, the nodes are called sephiroth.[2] The diagram is also used by Christian Cabbala, Hermetic Qabalah and Theosophy.[5][6][7] The diagram is believed to be derivable from the flower of life.[3]
