Qliphoth
The Qliphoth/Qlippoth/Qelippot or Kelipot ( Heb. קְלִיפּוֹת, the different English spellings are used in the alternative Kabbalistic traditions of Hermetic Qabalah and Jewish Kabbalah respectively), literally "Peels", "Shells" or "Husks" (from singular: קְלִיפָה Qliphah/Kelipah "Husk"), are the representation of evil or impure spiritual forces in Jewish mysticism, the polar opposites of the holy Sephirot. The realm of evil is also termed "Sitra Achra/Ahra" ( Aramaic סטרא אחרא, the "Other Side" opposite holiness) in Kabbalah texts.
