[547] In how many ways (katihākārehi) do the four truths (sacca) have a single penetration (ekapaṭivedha)?
What is impermanent (anicca) is suffering (dukkha);¹ what is impermanent and suffering is non-self (anattā); what is impermanent, suffering, and non-self is real (tatha); what is impermanent, suffering, non-self, and real is true (sacca); what is impermanent, suffering, non-self, real, and true is included under one (ekasaṅgahita); what is included under one is a unity (ekatta); one penetrates the unity with a single knowledge (ñāṇa) — thus the four truths have a single penetration.
In how many ways do the four truths have a single penetration? In nine ways the four truths have a single penetration: in the sense of what is real (tathaṭṭhena), in the sense of non-self (anattaṭṭhena), in the sense of truth (saccaṭṭhena), in the sense of penetration (paṭivedhaṭṭhena), in the sense of direct knowledge (abhiññaṭṭhena), in the sense of full understanding (pariññaṭṭhena), in the sense of abandonment (pahānaṭṭhena), in the sense of development (bhāvanaṭṭhena), in the sense of realization (sacchikiriyaṭṭhena). In these nine ways the four truths are included under one; what is included under one is a unity; one penetrates the unity with a single knowledge — thus the four truths have a single penetration.
