The motivation behind writing this book is to discuss with our reader that “HOW ONE CAN BE THE MASTER OF HIS/HER OWN EMOTIONS”. How we can got the better emotional stability? How we can develop an emotional intelligence on scientific ground. To fight with our emotions without understanding it on scientific ground is just like that we are trying to find door of a room without opening our eyes. So what exactly we are doing with our emotions we want to overcome from our Anger, fear, stress, anxiety, anguish, tensions, greed lust etc. But we don’t know exactly that what is Anger ?, What is fear?, what is Anguish ?, What is stress ?, what is greed? , what is Lust? . From where our emotions are originated what is the very source of our emotions we come to know anger only when it is manifested in our behavior. We are able to catch the stress only when it has been already manifested our behavior. We actual don’t know the very source of our emotions we aware about our mind states only when it has been changing our behavior and physiology we are unable to catch these emotions when it had been effecting our nervous system or our endocrine system. It is just like the case we are detecting cancer when it is in 3rd or 4th stage we are unable to catch our source of our emotions at initial state. So this book is about how we can identify our emotions like fear anger etc at very primarily state and how we can stop these emotions at very initial state.
