This metaphysical theology gives cosmic significance to the life of each person, as each individual has particular tasks that only they can fulfil. Therefore, gilgulim assist the individual soul in this cosmic plan. This also explains the Kabbalistic reason why the future eschatological Utopia will be in this World, as only in the lowest, Physical realm is the purpose of Creation fulfilled. Spiritual dimension of all Creations In Kabbalah, from its initial Medieval form onwards, Creation is described as a descending Chain of spiritual Worlds of cause and effect. The new 16th-century Kabbalistic paradigm of Isaac Luria extends the meaning of this with the concept of the holy sparks. Creation is a continuous process of Divine vitality. All physical and spiritual Creations only continue to exist due to the immanent Divine Ohr ("Light"), from God's Will to create, that they constantly receive. This immanent flow forms the spark of holiness in any Created form. This teaches that the true essence of anything is only its Divine spark within, that gives it continual existence. If the light were to be withdrawn, the creation would cease to exist. This complete dependence on Divinity is hidden in this lowest physical realm, but the souls and angels of successively higher spiritual realms are nullified to the Divine Unity, in successively higher degrees. This explains the statement of Isaac Luria that even stones possess a subtle form of soul. With the focus in Lurianic Kabbalah on Cosmic Tikkun rectification, accordingly every leaf also possesses a soul that "came into this world to receive a rectification". Above-conscious root of Gilgul 16th-century Lurianic doctrine was the first time that Kabbalah focused on gilgul, because it forms the microcosmic parallel to the Cosmic Divine rectification taught by Luria. In Medieval Kabbalah of the Zohar, which received its full rational synthesis in 16th-century Cordoveran Kabbalah, immediately before the new teachings of Luria, Gilgul was not the focus as intellectual categorisation was sought. Lurianic Kabbalah, accordingly, while also fully systemised in rational articulation, nonetheless focuses on Divine soul levels above intellect. The central doctrine of Luria is the Tzimtzum (Divine "Withdrawal") that paradoxically transcends human logic. The Tikkun rectification of the Tzimtzum, involving the "birur" (elevation) of the sparks of Creation, and their soul parallel of Gilgul, similarly are rooted in Divine levels above intellect. In the foundational Kabbalistic structure of the 10 Sephirot (emanations), Keter (Divine Will) transcends the
