Looks like some sort of hypnotism to me.
God never asks us to make our minds go blank, He tells us to
guard our minds.
that is what I believe, hypnotism invite the devil, when our mind blank, no logic anymore, then the devil come to deceive, no filter. I read an article, there was a man kill his father, he said to the police, on his meditations his dead grandpa come and ask him to kill his father. I believe in normal stage where his logic normally operate, he not just follow what he hears
