For some reason the great mystic of the Middle Ages, Rav Avraham Abulafia is not well known and that seems like a tragedy to me. After all, he was highly regarded by Rav Chaim Vital and the Remak רב משה  קורדבירו both. In fact, that last gate of the Musar book of Rav Chaim Vital, vol.  4 [שערי קדושה] consists almost entirely of the system of Rav Avraham Abulafia,  and does not even mention the Ari. Plus, the Remak quotes the books of Abulafia often in his Pardes [but does not mention the author.]

He did have an opinion about Jesus that is not well known. He held he was the messiah son of Joseph mentioned at the end of tractate Suka.  [The subject of messiah son of Joseph is dealt with also in the Kol HaTor of the Gra and the Ramchal. [That is the Tikunim Chadashim of the Ramchal].
