The objectives of this study were 1) to investigate the importance of precepts(Sīla) and views(Diṭṭhi) in Theravada Buddhist scriptures, 2) to study the unity and disunity in Theravada Buddhist scriptures, and 3) to study precepts and views as the causes of unity and disunity. The results of this study indicated as follows.

In terms of the importance of precepts and views in Theravada Buddhist scriptures, it was found that precepts derived from the rule of the emperor, referred to the root cause of well-controlled behavior and conduct. Precepts are the doctrine of physical and psychological control. There are two types of precepts, namely  monastic precepts and secular precepts. Individual elements of precepts are specific to the condition of abuse conduct. Precepts have many results of merit. Ditthi means views, consisting of two types, namely Sammaditthi and Mitchaditthi.

In terms of unity and disunity in Theravada Buddhist scriptures, it was found that unity means the collaboration under the balance of precepts and views. The doctrines leading to unity are Saraniyadhamma, Aparihaniyadhamma, and Sangahavatthu 4. In contrast, the disunity is an opposite side of unity. Disunity related doctrines are dissension(Sangkharachi and Sangkhaphet). The method of eliminating disunity is to rely on Athikarana Samatha, etc.  

Sila (Precept) which is the cause of unity is Sila-samannata. Dithi (View) which is the cause of unity is Dithi-samannata. The advantage of building unity is the emergence of  happiness, love, and respect. Disunity results in monastic and secular disadvantages.
