The aim of this paper is to introduce the meaning of the word Samasīsin, and to clarify its usage in Pāli Buddhist literature. According to the Pali English Dictionary, this word Samasīsin is simply endowed with the meaning “one who simultaneously attains an end of craving and of life.” This paper shows how this word is explained in Abhidharma materials and Pali Buddhist Commentaries.

The significance of this word is found in the consideration of the suicide problem in Buddhism. It is worth discussing as a theme because the usage of the word Samasīsin gives a logical explanation to the obtainment of arhatship by monks who committed suicide.
