2.521

諸佛賢聖所共稱歎。背生死苦示涅槃樂。十方三世諸佛所說　此五總結理也。肇曰。諸佛共稱以明共法必真也。生死雖苦背之至難。涅槃雖樂識之者寡。自非深經孰啟其路。諸佛雖殊其道不二。以明其第一義經常一不差也。美深經訖於是。

"'Praised in unison by the Buddhas, worthy ones, and holy ones, turning away from the suffering of saṃsāra and displaying the bliss of nirvāṇa, expounded by the Buddhas of the ten directions and the three times.'" / This fifth is the general conclusion regarding the principle. / Sengzhao says: "Being praised in unison by the Buddhas clarifies that their shared Dharma is necessarily true. Although saṃsāra is suffering, to turn one's back on it is exceedingly difficult; although nirvāṇa is bliss, those who recognize it are few. Were it not for the profound sūtras, who could open this path? Though the Buddhas are distinct, their Way is non-dual, demonstrating that this sūtra of the ultimate truth is ever one and unerring." Here ends the praise of the profound sūtra.
