What is the status of the Ari [Rav Isaac Luria] or the Remak [Moshe Cordoba]-if we notice that the Zohar is not really from R. Shimon ben Yochai? (note 1) But there was a mystic tradition.
I think the closer we get to areas outside of conditions of possibility of experience, the easier it is to get into worlds of delusions. So while the Ari and Moshe Cordoba were great tzadikim, it is hard to distinguish. to get an idea of legitimate continuance of the Ari, it is too easy to get involved in pure delusion. [The best that are okay, are the Reshash (Sharabi), Rav Yakov Abuchazeira, the Ramchal.]
(note 1) the world "although" in the Zohar is always expressed as "with all of this" עם כל דא and that is the Aramaic translation of עם כל זה and that is an expression invented by the Ibn Tibon family of translators during the Middle Ages. Therefore it could not have been written by R. Shimon ben Yochai.
