I found that the below scene from Lord of the Rings: The Two Towers depicts this perfectly. It is the scene where the ents march on Isengard. The orcs littering the ground are like the sweat and mud on your body. There are too many of them to take out individually. Hence, the ents are like you using a towel or your shirt; no matter how many times you swipe, there is some left and it will continue to bother you. When the orcs start to set the ents on fire, this is you being pushed to the breaking point of standing the discomfort. Then, the ents break the dam, which is you taking a shower. The water then flushes all of the orcs and their structures out as well as extinguishing the fires. This is the shower washing away all of the muck on your body and extinguishing your discomfort. Just like Isengard was cleaned of orcs, you are wiped clean of all the dirt and sweat.
