I remember hearing that there was a rabbi that used practical kabbalah with his disciples to fight SM' + LL', but I cannot remember his name.
Arizal has prohibited it, right? I remember that he gave names of some rabbanim who used it and made idol worship with practical kaballah, in that list includes the name of the rabbi of this history.
He grouped i think 4 disciples, then he made some meditations, so Elyahu appeared to him and said it wouldn't be possible, because SM'+LI' were too strong, but the rabbi was to give his life for Hashem, so Elyahu gave him some instructions, than after he made the things Elyahu said, angels appeared to him to give more complex instructions, all of them saying that he wouldn't succed. In the end, he gave some spices to SM', so it was considered as avora zarah, just one disciple survived to tell the history.
I would like to remember the name of this rabbi, so i could read the history again
