Are there any commentators that discuss the parallels between the rituals of biur chametz and tashlich? At a surface level, both involve destroying or eliminating bread, one via fire and one via water (which are symbolically opposite to one another). Chametz is broadly associated with the yetzer hara, and the bread that was cast into the water at tashlich symbolizes sins, so it seems clear that there are parallels. Are there deeper connections? Where are they discussed?
ETA: To clarify, I understand that halachically there is no similarity between the two practices. Symbolically, though, they seem similar ("destroying the chametz which represents our yetzer hara" vs. "casting away the bread to symbolize casting off our sins"). Something along those lines (but less superficial than what I have just written) is what I am wondering about. Does anybody else talk about this?
