We are born into this world unarmed - our mind is our only weapon.
For the activity of the mind is life.
Educating the mind without educating the heart is no education at all.
Place nothing above the verdict of your own mind.
Power-lust is a weed that grows only in the vacant lots of an abandoned mind.
All paid jobs absorb and degrade the mind
The energy of the mind is the essence of life.
The monotony and solitude of a quiet life stimulates the creative mind.
No great mind has ever existed without a touch of madness.
Age is an issue of mind over matter. If you don't mind, it doesn't matter.
