The way I see it is that our brain is the physical manifestation of our mind. Your mind is beyond your brain, your brain is merely an illusion of your mind in a physical plane.

If you imagine your mind, then you are using your mind to imagine itself. Oh but wait, your mind is an intangible object. How can an intangible object imagine itself? When I try to, I visualize a bunch of planes and empty space, a peek into planes beyond this physical reality. This is where the mind resonates.

However, you can use your mind to imagine your brain, since the brain is a tangible object. This physical plane is the core of all the planes that have come into existence due to our minds.
