The evil inclination, various flavors

Sukka 52a-b: The evil inclination

Most of today's daf (page) focuses on the yetzer ha-ra - the evil inclination. Rav Avira expounds: There are seven names given to the yetzer ha-ra: God called it ra - evil (see Bereshit 8:21) Moshe called it arel - uncircumcised (see Devarim 10:16) King David called it tameh - defiled (see Tehillim 51:12) King Solomon called it soneh - hated (see Mishle 25:21-22) Yeshayahu called it mikhshol - a stumbling block (see Yeshayahu57:14) Yehezkel called it even - a stone (see Yehezkel 36:26)  Yo'el called it hatzefoni - the hidden one (see Yo'el 2:20) One explanation for the different names is that they express different levels of evil, ranging from the latent evil that exists in every person (ra), to the ability of theyetzer ha-ra to hide the good from a person (arel), to act as an enemy by encouraging evil behaviors. Furthermore, even someone who tries to avoid it by casting it aside will find himself stumbling over it (mikhshol) in the form of a difficult to remove (even) temptation that is hard to even locate in order to avoid it, since it is hidden (tzafun) deeply in one's heart.
