The Gerona Circle writingsחוג גירונה

Ezra, Azriel, and Jacob ben Sheshet of Gerona took Isaac the Blind's whispered Provençal teachings and wrote them down (to their teacher's dismay — he protested the publicizing): Ein Sof formalized, emanation theorized, kavvanah and devekut given contemplative method. Azriel's "Gate of the Kavvanah" is a complete ascent-meditation in two pages. The Kabbalah's first school with a syllabus.
