Polar bear theory. Foreign name. Polar bear theory. Chinese abbreviation. White bear theory. Psychologists call this strange phenomenon the "mind control irony process."

That is, if you force yourself to do some ascetic spiritual training and self-enlightenment, it may only be counterproductive in the end. The reality of "the more you want to do well, the less you do well" will make you feel even more painful. And this kind of pain that is deliberately planted but does not bloom is just right and makes you miserable.

Apart from these theories, if you want to be happy, you must first clearly realize the fact that there is a "white bear" in your heart, and secondly, you must master the method of taming it.
