大般涅槃經集解 23.48

23.48

案僧亮曰：次顯口密也。如彼智臣善解密語，可以類求脩經之法也。以先陀婆譬四非常，一名四實。脩心常法者，知有常因，能得常果也。僧宗曰：第二明口密也。彼以一名表四種之實，此一偏教亦表常我四實理也。有智之人，因四非常悟於常樂。事同應身雖有三時，而識法身是常存也。

Sengliang comments: Next, the secret of speech is revealed. Just as that wise minister skillfully understood the secret words, by this analogy one may seek the method of cultivating the scripture. Taking "saindhava" as a parable for the four non-permanences, a single name designates four realities. Those who cultivate the eternal Dharma in their minds know that there is an eternal cause, and are thus able to attain the eternal fruit. Sengzong says: Second, clarifying the secret of speech. That minister used a single name to indicate four kinds of realities; likewise, this one partial teaching also indicates the four real principles of permanence and self. A person of wisdom, through the four non-permanences, awakens to permanence and bliss. This is identical in substance to the response body having three seasons, while recognizing that the dharmakāya is eternally enduring.
