The study is based on the Chinese translation of the Āgama scripture, discussing-the concepts of "sopadhi-śesa-nirvāna (extinction with remainder)" and "nirupadhiśesa-nirvana (extinction without remainder)". Also, it analyzes the thought of vimoksa (liberation)-"citta-vimukti (liberated mind)" and "prajñā-vimukti (liberated wisdom)", which are closely related to the "nirvāna (extinction)" concept. After organization, analysis and elaboration, the study sheds light on the internal link between "vimoksa (liberation)" and "nirvāna (extinction)", which should be maintained through practicing the Buddhist principle of "learning equally meditation and wisdom". In addition, the study points out the external distinction between the two, which can be explored from the perspective of "method" and "objective". At the same time, the study emphasizes that the standard which differentiates "sopadhi-śesa-nirvāna" from "nirupadhiśesa-nirvāna" whether according to the existence of "physical body" and "wisdom" or not, even though the Āgama Literature is a primary explanation to help followers to understand the significance of "nirvāna". Therefore, the study further explains the life-and-death elements which could cause worries and concerns hanging in a Buddhist practitioner's mind differentiate the two nirvāna.
