The things you do make the world you live in. In order to preserve the communal culture of a group they continue doing things that have no apparent function other than reinforcing the culture itself.  Who can say which parts of what we do are the ones that make us into ourselves and which parts are useless.  It is not your way, but it definitely has an obvious utility for the people engaging in it. Passing broad judgement against that utility because it&#x27;s outcomes are behavioral and mind-state rather than material is a reflection of your culture, not the senselessness of theirs.
