一正因佛性，二了因佛性，三緣因佛性，（此三者即三因佛性。）四果佛性，菩提之果也，正覺之智謂之菩提。五果果佛性，大涅槃也。以菩提之智，顯涅槃之理，故云果之果。法華文句十曰：「佛性有五：正因佛性通互亘《妙法蓮華經文句》卷10〈釋常不輕菩薩品〉：「正因佛性，通亘本當」(CBETA 2019.Q4, T34, no. 1718, p. 140c9)本當，了、緣，佛性種子本有，非適今也。果性、果果性，定當得之。」
The five characteristics of a Buddha' s nature: the first three are the 三因佛性 q. v., the fourth is 果佛性 the fruition of perfect enlightenment, and the fifth 果果佛性 the fruition of that fruition, or the revelation of parinirvāṇa. The first three are natural attributes, the two last are acquired.
