การศึกษาวิเคราะห์บทบาทของพระเทวทัตที่ปรากฏ ในคัมภีร์พระพุทธศาสนา

              The purpose of this research is the study Devadatta Bhikkhu’s biography in relation to other people and the effect of his action.
              Everything in this world has both good and bad points. It exists in every era. The Buddha was born for the happiness of mankinds. Devadatta Bhikkhu was born to hinder and ruin Him. His bad behavior only strengthened Lord Buddha’s perfections. It is like the black colour causing the white colour to be more bright.
               From the study, it is found that Devadatta Bhikkhu begun his feud towards the Buddha-to-be when he was born as a merchant named “Serîva”. And in other births, he also continued to creat the feud to the Buddha-to-be named Vessantara, while he was born as JÛjaka Brahman. He still took revenge against Lord Buddha. He more and more took revenge against Lord Buddha, because he was full of craving. He planned to govern the Order of Sangha, so he asked the Buddha to give him permission to do so; but he was rejected. For this reason, he tried to assassinate the Buddha many times; but he was not successful. Later on, he gradually declined, so he went to see the Buddha and asked Him for five conditions and cerated disagreement in the Sangha Oder. Finally he received the result of his bad action by being sucked into the soil.
               For one who was involved with Devadatta Bhikkhu, if he was a wise man, he would not get any bad result from him; but if he was foolish, he would not be able to distinguish what was right and what was wrong; and as a result, the evil would follow him. The ruins of all kinds would therefore arise to him more and more.
               Devadatta Bhikkhu is regarded as a wicked model for human beings, and so, he should not be followed by all of us, because one who follows his trace will receive all kinds of suffering.
