I read a paragraph similar to this from one of the writings of Swami Vivekanand and found it nice. Suppose there is a monkey with unstable mind, which is monkey's natural behaviour(some human also posses this behavior). He consumes alchohal making his mind more unstable. To make his unstability worse, a bee stings him. And now suppose a ghost also enters his body. Poor monkey!! Isn't he ?? Same is the case with human mind. Unstable because of his daily routine, lifestyle, interaction with different people, ideas. Similar to monkey, to make things more unstable, he drinks the alchohal of desire. Then a bee of jealousy stings him. And a ghost name proud enters his body to make the mind uncontrollable. What do you think would be the condition of this human. This is the case with all of us.
