Most people are not aware that the number one source of their suffering is the incessant, repetitive thoughts running in their mind.
It is not the headache or the life experience or situation that is so bad - it is the thoughts that you have about it that make it seem so god-awful!
So, some people think that "positive thinking" is the solution and they begin a wrestling match with their mind trying to change their thoughts....wow! What a impossible task!
