What does this confucius quote mean?

Wealth and rank are what men desire, but unless they be obtained in the right way they may not be possessed. Poverty and obscurity are what men detest; but unless prosperity be brought about in the right way, they are not to be abandoned. If man of honor forsakes virtue how is he to fulfill the obligations of his name? A man of honor never disregards virtue, even for the space of a single meal. In moments of haste he cleaves to it; in seasons of peril he cleaves to it.
