The mind is its own place, and in itself can make a heaven of hell, a hell of heaven..

Mind is not in any one place. Every cell in this body has its own intelligence. The brain is sitting in your head, but mind is all over the place.

The mind is everything. What you think you become.

The mind is its own place, and in itself / Can make a Heaven of Hell, a Hell of Heaven. / What matter where, if I be still the same...

What is mind? A heap of thoughts.

It's all in the mind.

Excuse me if I have/some place in my mind/where I go time to time.

[W]e are almost always in one place with our minds somewhere quite other.

So what is happening in your mind is your creation. Isn’t it so? World around you is just giving you information. The world is throwing pleasant information into you, unpleasant information into you; everything that is happening, it is just throwing it into you. What you do with this damn information is definitely yours. Yes or no?
When the activity of the mind is yours, the suffering that the mind generates is definitely your making. Would you generate unpleasantness and suffering for yourself if your mind was taking instructions from you? No. That means your mind is out of control.

It’s all in the mind.”

[W]e are almost always in one place with our minds somewhere quite other.” — Ford Madox Ford, Critical Essays of Ford Madox Ford

Mind has come up with this brilliant way of looking at the world — science — but it can’t look at itself. Science has no place for the mind. The whole of our science is based upon empirical, repeatable experiments. Whereas thought is not in that category, you can’t take thought into a laboratory. The essential fact of our existence, perhaps the only fact of our existence – our own thought and perception is ruled off-side by the science it has invented. Science looks at the universe, doesn’t see itself there, doesn’t see mind there, so you have a world in which mind has no place. We are still no nearer to coming to terms with the actual dynamics of what consciousness is.

The utmost mission of Mind is to train our obscure consciousness which has emerged out of the dark prison of Matter, to enlighten its blind instincts, random intuitions, vague perceptions till it shall become capable of this greater light and this higher ascension. Mind is a passage, not a culmination.

The mind is everything; what you think you become!
