觀音玄義記 2.31

2.31

八、簡本跡，二：初、本跡俱與拔，二：初、各具二用。二、「非本」下，相由貼文。非脫眾苦之跡，不顯一真之本，故前問答是明跡本。非證千如之本，莫垂十界之跡，故後問答是明本跡。二、「問本」下，本跡異真應，二：初、問；二、答。諸經所說，始從地住終至等妙，一分真明一分應起，豈唯一世實居當念？是名橫辯。別明本跡，如〈壽量品〉即今說久遠為本。諸經及跡門名已說近成為跡。既約久近，是故名就三世竪論。前明觀音多就體用而論本跡，今彰部故約久近而明本跡。

Eighth, distinguishing the original and the trace, in two parts: first, that both the original and the trace bestow and relieve, in two parts: first, each possesses both functions. Second, from 'Were it not for the original' onward, linking them together through the text. Were it not for the trace of liberating from all sufferings, the original of the single reality would not be revealed; therefore the earlier question and answer clarified the original from the trace. Were it not for the original of realizing the thousand suchnesses, one could not bestow the traces of the ten realms; therefore the later question and answer clarified the trace from the original. Second, from 'Question: The original' onward, that the original and the trace differ from the true and the responsive, in two parts: first, the question; second, the answer. What is expounded in the various sūtras, beginning from the stages and the abodes up to equal and marvelous [enlightenment], is that whenever one part of the true becomes clear, one part of the response arises; how could it be only in a single lifetime, when it actually resides in the present thought? This is called the horizontal discourse. Distinctly clarifying the original and the trace, as in the 'Foshouliang pin', now takes what is remote and distant as the original. What was expounded in the various sūtras and in the Trace Gate as recently accomplished is called the trace. Since it is based on the distant and the recent, it is therefore called vertical discourse across the three periods of time. The earlier clarification regarding Avalokiteśvara mostly discussed the original and trace in terms of substance and function; now, to manifest the distinctive character of this scripture, it clarifies the original and trace in terms of the distant and the recent.
