Politeness and Taharah
This is the key to a contrast Stephen Covey (most famous for “Seven Habits of Highly Effective People“) makes between his approach to self-help and the majority of the field. His book is about finding your core values and seeing how to implement them — including improving your relationships. To give an example Covey doesn’t make explicitly, Dale Carnegy deals with improvement by giving pragmatic and surface-polishing approach, “How to Win Friends and Influence People“.
In Mesukim MiDevash for Chukas, I identified the Jewish approach to the relationship between mind and the physical world with taharah. Taharah is also the term used for the purity of a metal — the menorah must be made of (pure gold). zahav tahor. Taharah, then, is the lack of adulteration of the mind with prejudices caused by the body. Free to choose when to pursue its physical needs and desires, man can consciously control his relationship to the physical world and the people we encounter in it.
Judaism looks to create ba’alei chessed, people who relate to this world primarily in terms of its opportunities to give and share with others. Not to simply be polite and act inoffensively. Which doesn’t quite work; backstabbing while smiling and using just the implications is a feature of “polite society”. But to actually have a relationship with the other.
