मोक्खमग्ग-गाई तच्चं, सुणेह जिणभासियं ।
चाउकारण-संजुत्तं, णाण दंसण लक्खणं ॥२८.१॥
Listen to the truth of movement on the path of liberation — spoken by the Jina, combined with four causes, and characterized by knowledge and perception.
This opening verse sets the stage for the entire chapter. The word "suṇeha" — "listen" — is an invocation of attention: what follows is not speculation or philosophy for its own sake, but the direct teaching of the Jina, the liberated omniscient one. The path of liberation is defined immediately by its four causes: right knowledge, right perception, right conduct, and right austerity — not four separate paths but four interlocking dimensions of a single transformative journey. The phrase "characterized by knowledge and perception" is significant: these two qualities are intrinsic to the soul itself. The soul is, by its very essence, a being of knowing and seeing — and the path of liberation is the restoration and purification of those essential capacities. The authority of this teaching rests entirely on the fact that it comes from the omniscient Jinas who have themselves walked the path to its end.
The simple version: The Jina taught us that the road to freedom has four essential parts: knowing rightly, seeing rightly, living rightly, and practicing discipline.
