Human mind is compared to a mad monkey.the monkey is restless by nature as all monkeys are .as if that it is not enough some one made him drink wine.so he became more restless .then a scorpion stung him .when a scorpion stings a man its unbearable pain and he jumps or a whole day so the poor monkeys condition is worse than ever and to complete his misery a demon entered his body in what language one can explain the uncontrollable relentlessness 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 the 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 .- Swami Vivekananda.
Every human mind is like this and some have some qualities in abundance and some just over do it .we all are blessed to be born as human and we have a million battles to win every day to survive and reality is some thing which we cannot escape and there are already enough things in every one lives to complicate it ,with our thinking and actions we Invite more and more problems to life.
Desire is some thing which makes people blind and its very apt to compare it with wine as lost in the desire we will not know what we are doing just we want it no matter what. and this is creating more and more problems and following a desire rather than a dream many people are lost in their life.
and Jealousy is the most awkward feeling in my opinion,he is having a latest this that , I don't have it thinking like this will only help increase you sorrows and wont do any good.
and lastly Pride which makes you think only I can do it and this is final nail in the coffin to completely get buried in sorrow for ever and all these are effective only when they are you masters .all these are a way of thinking you can change it this vey moment and it is in your hands.
Be the master of your mind not a slave . it is very hard to control a mind but it can be done many great people walked this way and showing us the path all we have to do is just walk it.
