The study deals with some of the central issues concerning the notion of death as discussed in Theravāda (Pāli Buddhism) as well as Mahāyāna Buddhism. What is the sense that death is regarded as an instance of duḥkha (Sanskrit) or dukkha (Pāli)? The research claims that here, firstly, the word duḥkha/dukkha is used as an adjective (which means ‘unsatisfactory’) rather than a noun (which means 'pain' or 'suffering'). Secondly, by death, the Buddha did not mean the act of dying but the experience of someone's death or the idea of death. The Buddha also talked about deathlessness as the goal. Here, deathlessness does not amount to accepting something eternal but developing a proper perspective towards death by meditations such as that on impurity ( аśubhabhāvanā ) and contemplation on death ( maraṇānussati ). If the cessation of the cycle of rebirths and re-deaths ( punarmṛtyu ) is the ultimate goal that the arhat (Sanskrit), or arahant (Pāli), achieves, then the same should apply to Tathāgata. In that case, the problem suggests itself: how could the question of Tathāgata’s existence after death be accounted for as an unanswerable ( avyākṛta )? The study opines that the reason behind this is the profound, immeasurable, unfathomable nature attributed to Tathāgata. The research also discusses the basic difference between the attitudes on death in Śrāvakayāna and Mahāyāna. Lastly, it deals with the question of whether termination of one’s own life is permissible in Buddhism under certain conditions.
