The study of the principles of Sammaditthi consisits of three objectives,i.e.,(1)to study Sammadhitti the principles from Tipitaka (The three baskets) and Theravada Scriptures; (2) to study and analyze happiness and peacefulness the principles from Tipitaka  and Theravada Scriptures; (3) to study and analyze the principles of Sammaditthi to build up happiness and peacefulness in Thai societies.

     The results of study found that that the knowledge of Sammaditthi are the right view; the right thought; and the right understanding to develop oneself to the final aim that is Nibbana.  Sammaditthi consists of two factors namely :- 1) Parato-Ghosa which means influences or the voices from the outside people who give the right suggestions (Kalaya-namitta); 2) Yoniso Manasikara which means the considering of  all things in depth, the setting up and making up the  decision of right thought and right view. However this knowledge focuses on Lokiya Sammaditthi , based on a right view in daily lives, which is the principle of how to deal with the happy life, and it is direct impact to initiate a  personal right thought, and a social level that will cause a peaceful society. Not only Sammaditthi but also the other related Dhammas to personal consideration of all kinds of problems, such as political, economic, social, environmental problems etc. At the same time, Meditation practice, brings happiness and peace to Thai societies, as well.

  In considering happiness as a holistic, the source of happiness is of two ways :-1) Inside happiness; it exists within mindfulness, and 2) Outside happiness, it is  related to many factors that came from the relationship between the human beings and the environment. Therefore a personal happiness is a social foundation. In addition, the Happiness in Buddhism consists of Lokiyasukha, which is a plain happy life, and Lokutarasukha, which is a plain happiness arising from mindfulness.

In fact , the proceeding of life following the  Tri – Sika (Sila, Samati, Panna) practicing way to improve to have the right thought and the right view. The qualifications of this are having an extreme enlightenment, extreme kindness for  others, and extreme happiness ,which will lead to the definite goal. That is creating the permanent peace in Thai society by expanding the happiness and peacefulness from the personal level to the societies.
