This proverb means that one should not judge a person solely based on their outer appearance, whether it is their body or face. Each individual has both positive and negative qualities, and it is unjust to reject someone purely on superficial grounds. In English, a similar proverb is ‘Don’t judge a book by its cover.’ It also serves as a reminder to be tolerant and to take the time to know people for who they truly are inside, rather than relying on quick and shallow judgments.
