二、約終教。即就真如性中立種性故，則遍一切眾生皆悉有性，故《智論》云「白石有銀性，黃石有金性，水是濕性，火是熱性，一切眾生有涅槃性，以一切妄識無不可歸自真性故。如經說言，眾生亦爾，悉皆有心，凡有心者定當得成阿耨多羅三藐三菩提。以是義故，我常宣說一切眾生皆有佛性。」

Second, according to the final teaching: because gotra is established within the nature of suchness, it pervades all sentient beings and all possess the nature. Thus the Mahāprajñāpāramitopadeśa says: 'White stone has the nature of silver; yellow stone has the nature of gold; water is of a wet nature; fire is of a hot nature; all sentient beings have the nature of nirvāṇa, because there is no deluded consciousness that cannot return to its own true nature.' As a sūtra states: 'Sentient beings are likewise: all possess a mind. All who possess a mind will definitely attain anuttarā-samyak-saṃbodhi. By this principle, I constantly proclaim that all sentient beings possess Buddha-nature.'"
