Tanya Chapter 22, Class 2 (166). From the perspective that there IS a world (ours) the first level are the ‘True” (Godly) worlds, and the second are the false (Klipa) worlds. We began this discussion today. Klipa (in Chassidus and Kabbalah) isn’t ‘evil’ (as we use the word), they are simply self-centered rather than God-centered. We focused a lot on the word טומאה (spiritual impurity or lack of cleanliness) and explained how refined this is (mystically) yet (at the same time) how real it is. We spent less time on the terms סטרא אחרא and קליפה and אלוקים אחרים because we will explore them at greater length (again) in Chapter 24 IYH.
