法華義疏 8.332

8.332

「是時疲極之眾心大歡喜」下，第三、稟教得益也。就文三別：一、信受；二、修行；三、證涅槃。說教稱機故稱歡喜。「歎未曾有」者，二種涅槃是出世之法，世間所無，名未曾有。「我等今者免斯惡道」，謂離生死苦也。「快得安穩」者，得涅槃樂也。至此已來皆是初聞佛教生信受也。

From "At that time the exhausted multitude rejoiced greatly in their hearts" onward, third, receiving the teaching and gaining benefit. In the text there are three distinctions: first, faithful acceptance; second, cultivation of practice; third, realization of nirvāṇa. Because the teaching matched their capacities, it is called "rejoicing". "Praising it as unprecedented" means that the two kinds of nirvāṇa are supramundane dharmas, not found in the world; hence called "unprecedented". "We now escape this evil path" refers to leaving behind the suffering of saṃsāra. "Quickly attain peace and stability" means obtaining the bliss of nirvāṇa. Up to this point, all belongs to first hearing the Buddha's teaching and giving rise to faithful acceptance.
