There was a monkey, restless by his own nature, as all monkeys are. As if that were not enough some one made him drink freely of wine, so that he became still more restless. Then a scorpion stung him. When a man is stung by a scorpion, he jumps about for a whole day; so the poor monkey found his condition worse than ever. To complete his misery a demon entered into him. What language can describe the uncontrollable restlessness of that monkey?
The human mind is like that monkey, incessantly active by its own nature; then it becomes drunk with the wine of desire, thus increasing its turbulence.
After desire takes possession comes the sting of the scorpion of jealousy at the success of others, and last of all the demon of pride enters the mind, making it think itself of all importance.
