This article aims to shed light on the possible influence of the Kabbalah on Spinoza. To do this, I will analyze the role that the Kabbalist theoretical model may have had on the development of Spinozist philosophy, in order to understand both their convergences and their divergences. I will then clarify Spinoza's relationship to this theory, especially the Lurianic Kabbalah, and emphasize the importance of the notion of Tsimtsum (contraction of the Divine light).
