Are you familiar with Rabbi Abraham Isaac Kook (1865-1935)? He was the first Ashkenazi chief rabbi of the British Mandate for Palestine [pre-state Israel] Simultaneously an Orthodox rabbi and an unabashed radical- today he would be considered heterdox.
Rav Kook was a mystic and Kabbalist – which usually isn’t quite my thing – but perhaps Rav Kook is the exception which proves the rule – His mysticism speaks to yearnings of the Jewish heart. Today he is highly regarded by Jews of all denominations/streams.
This book, from the Classics of Western Spirituality series, is a great collection of his thought: It includes complete English translations of Orot ha-Teshuva (“The Lights of Penitence”), Musar Avicha (“The Moral Principles”), as well as selected translations from Orot ha-Kodesh (“The Lights of Holiness”) and miscellaneous essays, letters, and poems.
* founder of the Religious Zionist Yeshiva Merkaz HaRav
* known in Hebrew by the acronym HaRaAYaH or simply as “HaRav.”
* one of the most celebrated and influential Rabbis of the 20th century.
