Siddhartha Gautama (Buddha) — "You will not be punished for your anger, you will be punished by your anger."

"An idea that is developed and put into action is more important than an idea that exists only as an idea."

"Three things can not hide for long: the Moon, the Sun, and the Truth."

"Even as a tree, though cut down, sprouts again if its roots are undamaged and strong, so also, if the roots of craving are not destroyed, suffering ever springs up again and again."

"To abstain from all evil, to cultivate the good, and to purify one's mind — this is the teaching of all Buddhas."

"There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations."
