 He established a yeshiva for Kabbalah study and actively recruited students.He wrote copious manuscripts in an appealing clear Hebrew style, all of which gained the attention of both admirers and rabbinical critics, who feared another "Shabbetai Zevi" (false messiah) in the making.His rabbinical opponents forced him to close his school, hand over and destroy many of his most precious unpublished kabbalistic writings, and go into exile in the Netherlands.
