“An insincere and evil friend is more to be feared than a wild beast; a wild beast may wound your body, but an evil friend will wound your mind.”

“What is evil? Killing is evil, lying is evil, slandering is evil, abuse is evil, gossip is evil, envy is evil, hatred is evil, to cling to false doctrine is evil; all these things are evil. And what is the root of evil? Desire is the root of evil, illusion is the root of evil.”

“More than those who hate you, more than all your enemies, an undisciplined mind does greater harm.”

“It is in a man's own mind, not his enemy or foe, that leads him to evil ways.”

“All that we are is the result of what we have thought: it is founded on our thoughts and made up of our thoughts. If a man speak or act with an evil thought, suffering follows him as the wheel follows the hoof of the beast that draws the wagon.... If a man speak or act with a good thought, happiness follows him like a shadow that never leaves him.”

“It is a great evil to look upon mankind with too clear vision. You seem to be living among wild beasts, and you become a wild beast yourself. ("“The Story of Prince Alasi and the Princess Firouzkah”)”

“Be vigilant; guard your mind against negative thoughts.”
