In the LeM of Rav Nahman [Collections of Rav nahman] you find the idea of Torah that comes from the halls of delusion. That is in volume I. Chapter 245.
In the השמטות [left out parts] you also find this idea of Torah of the Sitra Achra [the Realm of Evil]
The basic idea there is that there are Torah lessons which come from the kelipot [forces of evil].
That is to say --in order to merit to true and authentic Torah takes a great deal of self sacrifice in the service of God.
Not just people that cl;aim to be giving over Torah lessons, Rav Nahman finds highly suspect;-but also doing things which you think are good deeds ma very well not be good deeds. As the LeM starts out Vol I chapter 1 "the evil inclination is dressed in mitzvot" היצר הרע מתלבש במצוות
