Mind

"Open your eyes, train your ears, use your head. If a mind you have, then use it while you can."

"Everything that is really great and inspiring is created by the individual who can labor in freedom."

"You must read, you must persevere, you must sit up nights, you must inquire, and exert the utmost power of your mind. If one way does not lead to the desired meaning, take another; if obstacles arise, then still another; until, if your strength holds out, you will find that clear which at first looked dark."

"Where to look if you've lost your mind?"

"Most people believe the mind to be a mirror, more or less accurately reflecting the world outside them, not realizing on the contrary that the mind is itself the principal element of creation."

"There never can be a man so lost as one who is lost in the vast and intricate corridors of his own lonely mind, where none may reach and none may save."

"The face is a picture of the mind with the eyes as its interpreter."

"All problems are illusions of the mind."

"The mind of man is capable of anything."

"I mean, I have the feeling that something in my mind is poisoning everything else."

"It is the power of the mind to be unconquerable."

"At that moment I had no mind to change, or not change, or throw against the nearest wall."

"Your battles inspired me - not the obvious material battles but those that were fought and won behind your forehead."

"The mind can calculate, but the spirit yearns, and the heart knows what the heart knows"

"Nothing is at last sacred but the integrity of your own mind."

"The boldness of his mind was sheathed in a scabbard of politeness."

"It's all in the mind."

"My mind," he said, "rebels at stagnation. Give me problems, give me work, give me the most abstruse cryptogram or the most intricate analysis, and I am in my own proper atmosphere. I can dispense then with artificial stimulants. But I abhor the dull routine of existence. I crave for mental exaltation. That is why I have chosen my own particular profession, or rather created it, for I am the only one in the world."

"Reality exists in the human mind, and nowhere else."

"A man's mind is stretched by a new idea or sensation, and never shrinks back to its former dimensions."
