Need help to write an Essay on Perfume: The Story Of A Murderer: The narrator remarks

The narrator remarks, “Odors have a power of persuasion stronger than that of words, appearances, emotions, or will. The persuasive power of an odor cannot be fended off, it enters into us like breath into our lungs, it fills us up, imbues us totally. There is no remedy for it” [p. 82]. Do you think this is true? Why would an odor have such power? In what ways does Grenouille use this power to his advantage?
