Zachary Truboff’s “Torah Goes Forth From Zion: Essays on the Thought of Rav Kook & Rav Shagar” presents complex material clearly and enjoyably. Todd Berman reviews and recommends that for those seeking an entry point to the works of Rav Kook and especially Rav Shagar, but unable to access them in their original texts, Truboff’s project is highly recommended.
