To understand man`s intrinsic attributes, we have to know the essence of e power which enables man to live. What is the energy that sustains man? It may be said that it is energy which man gets by food which is physically needed to sustain the body. But man`s survival will which drives the man`s body does not derive from this kind of energy. It is from man`s energy to survive that gives him the energy and desire to exist. Man continues to live day after day by the energy of his desire. If there is no desire, man loses his will to live. So, it may be said that the ceaseless human desire has sustain him throughout history. Man, by his ceaseless desire, is continually trying to prove himself using destructive methods in order to succeed in his speech and behavior. Because of man`s destructive verbal abuse and behavior. man has accumulated negative karma, this negative karma causes more desires which cause harm to mankind, by the chain of cause and effect, incessantly causing a negative experience in reincamation. I attempt in this thesis to define the principles of karma and reincarnation by studying how the karma of man`s speech and behaviours which man`s vain desire has produced appears in real life, and to explain the substantial destiny of the characters in drama through the principles of karma and reincarnation.
