This quote suggests that the most significant difference between two people lies in their individual perceptions and standards of cleanliness. The term “cleanliness” here is not just limited to physical cleanliness, but also extends to mental, emotional, and moral cleanliness. The way people perceive and maintain cleanliness in these aspects can profoundly separate them.

For instance, someone might have a high standard of physical cleanliness, always keeping their environment neat and tidy, which could reflect their organized and systematic way of thinking. On the other hand, another person might not prioritize physical cleanliness as much but might have a high standard of moral cleanliness, always striving to be honest and fair. These different senses and degrees of cleanliness can create a deep divide between the two, as they reflect different values, attitudes, and ways of life.

In today’s world, this idea can be applied in various contexts. For example, in the workplace, employees might have different standards of professional ‘cleanliness’. Some might prioritize punctuality and precision, while others might value creativity and flexibility. These differences can lead to misunderstandings and conflicts if not properly managed.

In terms of personal development, understanding our own sense and degree of cleanliness can help us better understand ourselves and others. It can guide us in setting personal standards and goals, and in finding people who share similar values. It can also help us appreciate the diversity of human perspectives and learn from those who have different standards of cleanliness.

In conclusion, the quote suggests that our sense and degree of cleanliness, in its broadest sense, is a significant factor that distinguishes us from others. Recognizing and respecting these differences can lead to better understanding and harmony in our relationships with others.
