 Foundational texts of Medieval Kabbalism conceived evil as a demonic parallel to the holy, called the "Sitra Achra" (the "Other Side"), and the "Kelipot/Qliphoth" (the "Shells/Husks") that cover and conceal the holy, are nurtured from it, and yet also protect it by limiting its revelation.Scholem termed this element of the Spanish Kabbalah a "Jewish gnostic" motif, in the sense of dual powers in the divine realm of manifestation.In a radical notion, the root of evil is found within the 10 holy Sephirot, through an imbalance of Gevurah, the power of "Strength/Judgement/Severity".
