"The description of Shneur Zalman's teachings as a 'dynamic and often inharmonious body that changes and adjusts according to temporal circumstances' is a thoughtful way of approaching the textual mire of Hasidic sources. Tworek draws upon various corpora without attempting to systematize the teachings into a coherent theological system, revealing their vitality through his analysis of this critical theme." — Ariel Evan Mayse, editor of From the Depth of the Well: An Anthology of Jewish Mysticism
