(R. Shmuel bar Nachmani citing R. Hoshayah): If one says to an idol "you are my god", R. Akiva and Chachamim argue about this. (R. Akiva holds that one is Chayav Chatas for blasphemy b'Shogeg, for speech is considered an action - Bavli Kerisus 3b).

Question: If one bowed to an idol, what is the law? (Is this considered an action to be Chayav Chatas b'Shogeg?)

Answer #1 (R. Yochanan): All agree that if he bends his stature, he is liable.

Question (R. Aba bar Zimna, to R. Zeirah): What is the difference between lifting and lowering his stature, and lifting and lowering his lips? (Chachamim exempt for the latter!)

Answer (R. Yochanan): [All agree that speech is an action. Chachamim exempt Megadef] because it depends on intent.

Answer #2 (Reish Lakish): They argue [about bowing just like they argue about blasphemy. We explained the Sugya like KORBAN HA'EDAH.]

(R. Zeirah): [A Drashah on] a verse supports Reish Lakish. "Torah Achas Yihyeh Lachem la'Oseh bi'Shgagah" refers only to an action. What is the source for Megadef and bowing, which are not an action? (This shows that there is an opinion that does not consider bowing to be an action.)
