Fourth, clarifying the elucidated by distinguishing the principle of the one truth also has three aspects: first, properly clarifying the principle elucidated; second, clarifying the teachings that elucidate [it]; third, referencing the sūtras and treatises. First, clarifying the principle elucidated: this is the principle of the one truth. What is named the one truth? 'Truth' means truly verified. Dharmas that are truly verified are non-dual; how could there be three truths or two truths? All are called truly verified. Now, clarifying ultimate and conventional as being spoken of as truths is merely an expedient, not genuinely truths. Thus the *Nirvāṇa Sūtra* states: "What are called the two truths are in fact one. The Tathāgata merely uses expedients to transform sentient beings, and therefore speaks of them as two. For example, the sun and moon do not revolve, but a drunk person sees them revolving. You should know that there is only the non-revolving sun, seen alike by those who are not drunk; how could there separately be a revolving sun? If there were truly a revolving sun, those who are not drunk should also see it together." The one truth is like the true sun; the two truths are like the revolving sun. The true sun is truly verified, and may be called the one truth. The revolving sun is unreal; how could there be two truths? Speaking expediently of two does not constitute genuine meaning; hence they are not truths. Here, the one real truth is taken as the principle elucidated.
