2.15

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.'"
