Mind is a thought, whether you say that it is what you have or what you are. So much of thought goes into providing a setting for ongoing thinking, a setting made of nothing but thoughts. You imagine that there is something that needs to be made clear, you worship logic which is an acquisition of thought to yield further thoughts. And the hindrances to understanding, how complex and refined they grow, only more notions piled on top of notions. It is not logic which yields the impossibility of hindrances. You can't be freed from the house of thought by adding more storeys. You are part of the furniture, why not go out by the same way that you went in leaving yourself behind?
