Answer

Indeed, there are various ____________ that a person needs, to be worthy of נבואה. However, in these הלכות the רמב"ם is explaining our belief in נבואה itself.

Since the נביא experiences Hashem’s revelation through נבואה specifically in his ______, the רמב"ם only highlights the quality of the נביא’s wisdom.
