" 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. How hard to control such a mind! "
