It teaches more about culture in general. You would get "used" to your culture. Let's say your Muslim and you don't pray often, once you do you'll be used to it and pass it on to your children and enrich your culture. Culture could mean anything from clothes to decor. Passing it down to future generations would enrich it. Hope this helps (;❤️
