"Pools of sorrow, waves of joy are drifting through my opened mind Possessing and caressing me"

that is the single most important line in this song because it helps us to truly understand what Lennon was thinking, nothing. to have an open mind is to be completely open to the world around him and to experience life as it was meant to be experienced. to receive that "limitless undying love" one must be open to it and not be held back by the minds own ramblings.

"Thoughts meander like a restless wind inside a letterbox They tumble blindly as they make their way across the universe"

his thoughts are there and he is aware of them, but he pays them no mind. he locks them away and puts them inside a box. he knows that all negativity is an illusion created by the mind. the only real in his life was what he could actually experience and this song is about how wonderful it is when you stop letting your thoughts rule you.

OK - but don't be so open-minded that your brains fall out.

@selfevidenttruth he doesn't lock them inside a box he lets them ride over him and accepts them as they are rather than concentrating on them he is just letting them flow throughout himself, unquestioning. the world will be as it is and that's just it. you can either worry about your thoughts and try and push them aside or you can accept them as they are and remember that everything is the way its meant to be,so why even worry about trying to put them away. just let them be what they are and let go of control.
