Perek 8, Class 2 (82) שד משדין יהודיין versus שד משדין נוכראין. A Jew by nature has no desire to sin, even in his Yetzer HaRa. There is a טבע or limit to the Evil inclination (יצר הרע) of a Yid that comes through what is called שד משדין יהודיין. This means that it has natural limits, and that sins are outside of that limit and need to be “learned” (see קונטרס ומעיין מאמר ב’ פרק א). [A Goy also has a Teva that disallows him to transgress any one of his Seven Mitzvos, and he too is only able to sin by going lower than his nature (through רוח שטות).
