 From there Kabbalah spread to Catalonia in north-east Spain around the central Rabbinic figure of Nahmanides (the "Ramban") (1194–1270) in the early 1200s, with a Neoplatonic orientation focused on the upper sephirot.Subsequently Kabbalistic doctrine reached its fullest classic expression among Castilian Kabbalists from the latter 1200s, with the "Zohar" (Book of "Splendor") literature, concerned with cosmic healing of gnostic dualities between the lower, revealed male and female attributes of God.Rishonim ("Elder Sages") of exoteric Judaism who were deeply involved in Kabbalistic activity, gave the Kabbalah wide scholarly acceptance, including Nahmanides and Bahya ben Asher ("Rabbeinu Behaye") (died 1340), whose classic commentaries on the Torah reference Kabbalistic esotericism.
