第三明起說意，同意上說諸法皆離言說，何故諸佛於離言法而起言說，說若稱法法非離言，云若違法說即不益？答有四：一、不能為他說；二、不說他不聞；三、不聞他不知；四、為令他知可聞故諸佛言說意者。法雖無言，欲令他知無言之法，以方便假名相說。若不起說他不聞知離言一法，諸佛菩薩為利他故無名中假名想說，此即藉言以顯無言。

The third part explains the intention behind producing the teaching. Agreeing with the aforementioned statement that all phenomena are transcendent of verbal expression: why do the Buddhas produce verbal expression with regard to phenomena that are transcendent of words? If the expression corresponds to the phenomenon, the phenomenon is not transcendent of words; if the expression contradicts the phenomenon, then the teaching provides no benefit. The answer has four points: first, one cannot teach for others; second, without teaching, others do not hear; third, without hearing, others do not know; fourth, it is in order to cause others to know through what can be heard. Thus, the intention of the Buddhas' verbal expression is that although phenomena are devoid of words, wishing to cause others to know the wordless phenomena, they speak using the marks of expedient provisional designations. If they did not produce the teaching, others would not hear and know the single phenomenon that is transcendent of words. For the benefit of others, Buddhas and bodhisattvas speak through provisional names and conceptualizations within that which is nameless; this is relying on words to reveal the wordless.
