This study is of  three purposes namely: 1) to study the Buddhist codes in Vinaya-Pitฺaka,  2) to study the violation of the Buddhist rules by the Chabbaggiya Bhikkhus and 3) to analytically the violation of  the Buddhist rules by the Chabbaggiya Bhikkhus.

                   From the study, it is found that the Buddhist rules mean the rules of discipline and the order which the Buddha laid down for regulating the monks’ actions.  They were the roots of Buddhism called “Vinaya or 227 rules” that are established because of the monks’ misconducts by being criticized by the lay people.  After investigating and knowing the fact, the Buddha laid down the monastic rules.

                   The six ascetics were:  Pañdฺuka,  Lohitaka,  Mettiya,  Bhummajaka,  Assaji, and  Punabbasuka who were original friends before the ordination. They were known as  “Chabbaggiya Bhikkhus”  meaning the six ascetics. They conducted themselves improperly owing to their habitual impiety and stubbornness that were their personal habits and shamelessness toward the wrong-doing and the monastic rules. They extremely undermined Buddhism and became the causes of the Buddha’s laying-down called Ãdikmmika. They became the causes of laying-down the 132 rules in both root-rules and additional rules, namely 2 Pãrãjikas, 3 Sanghãdisesas, 12 Nissaggíyapãcittíyas, 42 pãcittíyas, 1 Pãtฺidesaníya, and 72 Sekhiyavattas. Apart from this, there are still several rules outside the  codes of the fundamental rules.

                   Six Chabbaggiya Bhikkhus were of the bad examples for later generations not to follow, because if anyone followed them, the result was a bad reputation, and will be a blame including the bad manner which was not the endowment of the faith by general people. As a result, the later generations do not progress in the Buddha’s doctrines and disciplines called  “Nibbãna” which is the ultimate goal in Buddhism.
