No, explain what the meaning is.

When you have real misery or trouble.
Not a problem in the form of “the boss shouted,” “on the road they were bullied,” “mama didn’t give the pocket,” “the neighbor’s iPhone is cooler,” etc., and the real trouble – when really no one and nothing can help.
In short, if this happens, then you will immediately understand - and what they give, and what the meaning is.
As one good man sang, "when you are going to drown, you will understand why you needed a shore."
And you will run like a cute - and to the church, and to the grandmothers, and to the extrasensors, and to the devils for the sake of even a miserable chance to change something. This is called hope and faith.
These two things are irrational in their essence.
To try to evaluate them from the point of view of household logic or benefits (things purely rational) is to demonstrate your own, gently speaking, stupidity and limitation ;-)

There was a serious illness in a loved one, did not run. Probably because time, strength and resources were very lacking then, and I preferred to spend them on fighting the disease and comforting the patient, rather than on bats with an unclear purpose. By the way, everything was resolved safely without any charlatans. So about stupidity you are, do not judge by yourself.
