Sha'arei Orah (Gates of Light)שערי אורה

Joseph Gikatilla's masterpiece: the definitive map of the divine names — which Name operates which sephirah, and how the whole nervous system of appellations interconnects. The book to read when you want the Tree as switchboard. Gikatilla began as Abulafia's student and brought that letter-fluency into theosophic Kabbalah: both rivers in one channel.
