According to the Mahaparinibbana Sutta of the Pali canon, at the age of 80, the Buddha announced that he would soon reach Parinirvana or the final deathless state abandoning the earthly body. After this, the Buddha ate his last meal, which, according to different translations,especially the religious texts knowledge of Heenyan texts was pork, which he had received as an offering from a blacksmith named Cunda. Falling violently ill, Buddha instructed his attendant Ānanda to convince Cunda that the meal eaten at his place had nothing to do with his passing and that his meal would be a source of the greatest merit as it provided the last meal for a Buddha.

The Mahayana Vimalakirti Sutra explains, in Chapter 3, that the Buddha doesn't really become ill or old but purposely presents such an appearance only to teach those born during the five defilements the impermanence and pain of defiled worlds and to strive for Nirvana.

"'Reverend Ánanda, the Tathágatas have the body of the Dharma - not a body that is sustained by material food. The Tathágatas have a transcendental body that has transcended all mundane qualities. There is no injury to the body of a Tathágata, as it is rid of all defilements. The body of a Tathágata is uncompounded and free of all formative activity. Reverend Ánanda, to believe there can be illness in such a body is irrational and unseemly!' Nevertheless, since the Buddha has appeared during the time of the five corruptions, he disciplines living beings by acting lowly and humble."[14]

Ananda protested Buddha's decision to enter Parinirvana in the abandoned jungles of Kuśināra (Pāli: Kusināra) of the Mallas. Buddha, however, reminded Ananda how Kushinara was a land once ruled by a righteous wheel-turning king that resounded with joy:


44. Kusavati, Ananda, resounded unceasingly day and night with ten sounds -- the trumpeting of elephants, the neighing of horses, the rattling of chariots, the beating of drums and tabours, music and song, cheers, the clapping of hands, and cries of "Eat, drink, and be merry!"

Buddha then asked all the attendant Bhikshus to clarify any doubts or questions they had. They had none. He then finally entered Parinirvana. The Buddha's final words were, "All composite things pass away. Strive for your own liberation with diligence." The Buddha's body was cremated and the relics were placed in monuments or stupas, some of which are believed to have survived until the present. For example, The Temple of the Tooth or "Dalada Maligawa" in Sri Lanka is the place where the relic of the right tooth of Buddha is kept at present.

According to the Pāli historical chronicles of Sri Lanka, the and , the coronation of Aśoka (Pāli: Asoka) is 218 years after the death of Buddha. According to one Mahayana record in Chinese (十八部論 and 部執異論), the coronation of Aśoka is 116 years after the death of Buddha. Therefore, the time of Buddha's passing is either 486 BCE according to Theravāda record or 383 BCE according to Mahayana record. However, the actual date traditionally accepted as the date of the Buddha's death in Theravāda countries is 544 or 543 BCE, because the reign of Aśoka was traditionally reckoned to be about 60 years earlier than current estimates.

At his death, the Buddha told his disciples to follow no leader, but to follow his teachings (dharma). However, at the First Buddhist Council, Mahakasyapa was held by the sangha as their leader, with the two chief disciples Mahamoggallana and Sariputta having died before the Buddha.
