 In Hasidic Panentheism, the world is acosmic from the Divine view, yet real from its own perspective.Around the 1230s, Rabbi Meir ben Simon of Narbonne wrote an epistle (included in his "Milḥemet Mitzvah") against his contemporaries, the early Kabbalists, characterizing them as blasphemers who even approach heresy.He particularly singled out the Sefer Bahir, rejecting the attribution of its authorship to the "tanna" R. Neḥunya ben ha-Kanah and describing some of its content as truly heretical.
