涅槃是佛教修行所要達到的最高目的，是佛教哲學的基本觀念。本論文專題探討龍樹中觀學的涅槃學說。中觀學的涅槃學說是建立在緣起性空基礎之上，所謂涅槃即是指聖人以般若智證入諸法性空的狀態，而大乘佛教解脫論的旨趣即是生死與涅槃不二。龍樹中觀學重視以般若智慧觀空得涅槃的方法，並站在大乘佛教菩薩道的立場，提出不住涅槃不住生死的無住涅槃說。龍樹中觀學並不是以聖者灰身滅智為涅槃，而是以完全的淨化生命形式證入宇宙一元的性空法身為涅槃。

Nirvāna, as the final status of relief, is the most important and fundamental concept in Buddhism philosophy. In this paper we will discuss the concept of Nirvana in Mādhyamika. The Mādhyamika's main idea is Dependent Origination and the Emptiness of Nature. Na^ga^rjuna insitsted that nervikalpanaing the Emptiness of Nature could lead to Nirvāza, and made us attain the nibbāna-dhāta. In his point of view, there is no precise parallel to distinction of the nibbāna-dhāta and the Secular world. In Mādhyamika, dhamakāya is regard as the approach to the nibbāna-dhāta. From the practices of the bodhisattva (bodhisativa-carya^), Na^ga^rjuna brought forward that the Sanskrit bodhisattva did not stick to the nibbāna-dhāta and the transmigration, which is called the apratisthita. From the standpoint of the Hinayana, the concept of Nirvāna means to exterminate the transmigration of soul, and cease the life thoroughly. But Na^ga^rjuna didn't with this point. He insisted that the tathatām or the voidness (shanyata) was the spiritual body of Buddha (dhamakāya). So the concept of Nirvāna in Mādhyamika means unite of the spiritual body and the individual, which is the exclusively purificatory life without any desire, anger and ignorance.
