The mind just doesn't know its way to the answers you're looking for. The intellect doesn't know. But the mind is what you know to use, so you go there. You have a problem in your life, a dilemma, something you really need to figure out. So you go to thought. Go to the mind. Go to intellect.
And you find it's just not giving you what you need. No answers. Just more frustration and more circular thinking. The quality of it all spirals down. And the more you look to the mind for answers, the further you travel from those answers. And the further you get, the more desperately you go to mind. Vicious circle, see.
