How hard it is to control the mind....

How hard it is to control the mind! Well has it been
compared to the maddened monkey. There was a monkey,
restless by his own nature, as all monkeys are. As if that
were not enough, someone 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 jealously of others whose desires meet with
fulfilment, and last of all the demon of pride takes
possession of the mind, making it think itself of all
importance. How hard to control such a mind!
