Joseph Gikatilla
Gikatilla's most famous work, 'Sha'are Orah' (Gates of Light), is considered a seminal text in the study of Kabbalistic thought. In this and other works, he elaborates on the dynamic interplay between the sefirot and the divine essence, offering a complex system of spiritual ascent for the mystic. Gikatilla's teachings had a lasting impact on later Kabbalists, including the influential Isaac Luria. Despite the esoteric nature of his writings, Gikatilla's work remains accessible and continues to be studied by those interested in Jewish mysticism and Kabbalah.
