1.9

第六、釋本覺本不覺，各有三門：一、開義，二、由起，三、和合。初者、本覺有三義：一、無不覺義；二、有本覺義；三、無本覺義。不覺亦三義，一、無本覺義；二、有不覺義；三、滅不覺義。二、由起者，由無不覺故，得有本覺；由有本覺故，得成不覺；成不覺故，名無本覺也；由無本覺故，得有不覺；由有不覺故，得有性滅，故名滅不覺也。又由不覺中有無本覺義故，得有本覺義。又由本覺中有無不覺義故，得有滅不覺義。又由本覺中有本覺義故，不覺中得有無本覺義也。又上諸義相由，各各無二，共合成三句。又依本覺得成不覺，不覺能知名義得成始覺。始覺成故，不覺則滅；不覺則滅故，始覺則同本覺；同本覺故，則無始覺；無始覺故，則無不覺；無不覺故，則無生滅門，唯一真如門也。是故當知至心源時，唯是真如，無生滅；無生滅故，亦不可說真如，豈有三身之別？但隨眾生染機故，故說三身等也。

Sixth, in explaining original enlightenment and original non-enlightenment, each has three gates: 1. unfolding meanings; 2. origin and arising; 3. composite integration. As for the first: original enlightenment has three meanings: 1. the meaning of having no non-enlightenment; 2. the meaning of having original enlightenment; 3. the meaning of having no original enlightenment. Non-enlightenment also has three meanings: 1. the meaning of having no original enlightenment; 2. the meaning of having non-enlightenment; 3. the meaning of extinguishing non-enlightenment. Second, regarding origin and arising: because there is no non-enlightenment, there can be original enlightenment; because there is original enlightenment, non-enlightenment can be formed; because non-enlightenment is formed, it is called having no original enlightenment; because there is no original enlightenment, there can be non-enlightenment; because there is non-enlightenment, there can be the extinction of nature, hence it is called extinguishing non-enlightenment. Furthermore, because within non-enlightenment there is the meaning of having no original enlightenment, there can be the meaning of original enlightenment. Furthermore, because within original enlightenment there is the meaning of having no non-enlightenment, there can be the meaning of extinguishing non-enlightenment. Furthermore, because within original enlightenment there is the meaning of original enlightenment, within non-enlightenment there can be the meaning of having no original enlightenment. Moreover, the above meanings originate mutually, each being non-dual, together forming three propositions. Furthermore, relying on original enlightenment, non-enlightenment can be formed; when non-enlightenment can know names and meanings, initial enlightenment can be formed. Because initial enlightenment is formed, non-enlightenment is extinguished; because non-enlightenment is extinguished, initial enlightenment is identical to original enlightenment; because it is identical to original enlightenment, there is no initial enlightenment; because there is no initial enlightenment, there is no non-enlightenment; because there is no non-enlightenment, there is no aspect of arising and ceasing—there is solely the one aspect of tathatā. Therefore, one should know that upon arriving at the source of the mind, it is purely tathatā, without arising and ceasing; because there is no arising and ceasing, one cannot even speak of tathatā, so how could there be the distinction of the three bodies? It is only in accordance with the defiled capacities of sentient beings that the three bodies and so forth are spoken of.
