Religions have a history of making up bullshit reasons why suffering and being unhappy is the righteous path. Christianity promises you a happy afterlife for suffering in real life, Hinduism tells you that you're getting karmic credit points for your next life, etc. "facing your suffering" is just another iteration of this.

A more rational take on these teachings is that historically they were a tool of pacifying the masses to accept their abject poverty and squalor without revolting and imploding the social hierarchy. They make no sense in a post-scarcity world.

This is what I mean by religious bullcrap.
