Why did you bring up your religion in the first place? OP said that he found this cool technique for instant relaxation, and then you started talking about whatever religious bullcrap.
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.
Hinduism doesn’t have “karmic credit points” and this is a misconception. Karma is the output of the totality of your life and its measurement is cosmically obscured. You can, however, be granted awesome boons by the various deities for extreme selfless acts of devotion —- demons included.
It hasn't been only "discovered" there, definitely not... and even if so, religion or whatever is the truth and noone dare to use it differently ( what OP even not said), bad cultural appropriation or what?
