Imam Ali ibn Abi Talib (A.S.) on Mind

"Often your utterances and expressions of your face leak out the secrets of your hidden thoughts."

"Recitation of the Qur'an without contemplation and thought is futile."

"Boasting issues from small minds."

"Self-conceit poisons the mind."

"If you ever feel any pride or vanity on account of your sway and rule over your subjects then think of the supreme sway and rule of the Lord over the Universe, the extent of His creations, the supremacy of His Might and Glory, His Power to do things which you cannot even dream of doing and His control over you which is more dominating than that which you can ever achieve over anything around you. Such thoughts will cure your mental weakness, will keep you away from vanity and rebellion , will reduce your arrogance and haughtiness and will take you back to the sanity which you had foolishly deserted... Try carefully to realize that a ruler can create goodwill in the minds of his subjects and can make them faithful and sincere to him only when he is kind and considerate to them, when he reduces their troubles, when he does not oppress them and when he never asks for things which are beyond their power. These are the principles which you should keep in mind and act upon."

"Never say to yourself, "I am their Lord, their ruler and all in all over them and that I must be obeyed submissively and humbly" because such a thought will unbalance your mind, will make you vain and arrogant, will weaken your faith in religion and will make you seek support of any power other than that of Allah."
