The gemara in Sotah 3a states:
ריש לקיש אמר אין אדם עובר עבירה אא"כ נכנס בו רוח שטות שנא' (במדבר ה, יב) איש איש כי תשטה אשתו תשטה כתיב
Reish Lakish says: A man commits a transgression only if a spirit of foolishness [shetut] enters him, as it is stated: “If any man’s wife goes aside [tisteh]” (Numbers 5:12) written tishteh
Q: What is this "spirit of foolishness" referring to- what does it mean?
(thinking out loud 🤔)
- are we literally talking about a spirit?
- if so, where would such a spirit come from
- what would trigger this spirit
- couldn't one argue that sinning is beyond a person's control? After all, the aveirah was committed when the person was overtaken by said "spirit"
