There was a great tzaddik and talmid chacham, R’ Yosef Caro (1488-1575). He was mechaber the Shulchan Aruch and many other works. He was zocheh to tremendous giluyim min hashamayim over a 35-year period. He had a malach appear to him constantly who related to him a lot of sodos (secrets). R’ Chaim Volozhin writes in his introduction to the Biur HaGra on Safra Ditzniusa, that it is not a pele that chachmei Yisrael are zocheh to such giluyim, that they open up the shaarei shamayim for them.
