滅度 是什麽意思，佛學如何解釋？

佛學大詞典 對“滅度”解釋如下：滅度 梵語nirva^n!a，巴利語nibba^na。謂命終證果，滅障度苦。即涅槃、圓寂、遷化之意。此謂永滅因果，開覺證果。即永遠滅盡‘分段、變易’等二生死，而度脫‘欲、有、見、無明’等四暴流。（參閱‘涅槃’4149）丁福保佛學大詞典 對“滅度”解釋如下：滅度　（術語）梵語Nirv&amacron;na，巴Nibb&amacron;na之譯，有有余無余之二（見涅槃條），故皆指命終證果。無量壽經上曰：‘國中天人不住定聚，必至滅度者，不取正覺。’法華經序品曰：‘佛此夜滅度如薪火滅。’遺教經曰：‘世尊滅度，壹何疾哉。’涅槃經二十九曰：‘滅生死故，名為滅度。’肇論曰：‘滅度者，言其大患永滅，超度四流。’行願品鈔四曰：‘言涅槃者，具雲般涅槃那，古譯為入滅息。息即是滅故，但雲入滅，或雲滅度，即滅障度苦也。’佛教英漢對照詞典 對“滅度”解釋如下：滅度Extinction == 滅度It means having put the Two Obstacles, I.e. the obstacle of afflictions and the obstacle of what is known, to an end. It also means that the beings have transcended the Two Deaths, I.e. glare-sectioned birth and death and changed birth and death.陳義孝佛學常見辭匯 對“滅度”解釋如下：滅度　即涅槃。滅是滅見思塵沙，無明三種惑，度是度分段變易兩種生死。
