大般涅槃經義記 3.274

3.274

文中有二：一明眾生有如來性可以趣入、二「方等經如甘露」下教人趣入。前即所證，後即能證。前中復二：一正明有性、二「迦葉白佛實無我」下問答重顯。前中，初明凡夫眾生有性不見，嬰孩喻下明二乘人有性不見。前中，先問二十五有有我不也？問由何生？如來向言世雖說我，無有佛性；迦葉知有，所以為問。下佛答之，佛性之義如別章釋。文中，初法，次喻，後合。

Within the text there are two parts: first, clarifying that sentient beings have the tathāgata-nature which can be entered; second, from 'The vaipulya sūtras are like nectar' downward, instructing people to enter. The former is what is realized; the latter is that which can realize. Within the former there are again two parts: first, directly clarifying the existence of the nature; second, from 'Kāśyapa addressed the Buddha: Is there truly no self?' downward, questions and answers reaffirming it. Within the former part, it first clarifies that ordinary sentient beings have the nature but do not see it; from the simile of the infant downward, it clarifies that people of the two vehicles have the nature but do not see it. In the former part, it first asks: Is there a self in the twenty-five states of existence, or not? From what does this question arise? The Tathāgata had just said that although the world speaks of a self, there is no buddha-nature; Kāśyapa knew it exists, and therefore asked. Below, the Buddha answers; the meaning of buddha-nature is as explained in a separate chapter. In the text, there is first the dharma, next the simile, and then the application.
