“The mind, stretched to new dimensions by images, thoughts and ideas, can never return to its former shape.”
“The mind, once stretched by a new idea, never returns to its original dimensions.”
“Man’s mind, once stretched by a new idea, never regains its original dimensions.”
“Once your mind stretches to a new level it never goes back to its original dimension”
“A man's mind is stretched by a new idea or sensation, and never shrinks back to its former dimensions.”
