In the Pāli canon, the terms dukkha and domanassa are used with reference to different types and degrees of suffering that must be understood according to context. This article first examines the meaning of puthujjana in the Pāli Nikāyas. It then analyses the contextual meanings of dukkha and domanassa, including a discussion of their types based on a thorough investigation of the Pāli Nikāyas. Finally, it examines the explanation in the Pāli Nikāyas of the arising of dukkha and domanassa, and, in particular, how lust, hatred, delusion and some other negative emotions are considered to cause physical pain and mental pain among puthujjanas.Mahidol UniversityArts and HumanitiesArticleSCOPUS
