Summary: In the Abhidhamma, sacca primarily refers to the Four Noble Truths (ariya-sacca) that define the Buddhist view of existence and liberation. The Vibhaṅga's fourth chapter, the Saccavibhaṅga, provides a detailed analytical exposition of these four realities: suffering (dukkha), the origin of suffering (samudaya), the cessation of suffering (nirodha), and the path leading to the cessation of suffering (magga) (Vibh 4).
Canonical locus
The Vibhaṅga defines the four truths by enumeration and provides a technical breakdown of each truth's components. (Vibh 4)
Vibh 4 (vb4:1.1–1.2)
Cattāri ariyasaccāni—dukkhaṁ ariyasaccaṁ, dukkhasamudayaṁ ariyasaccaṁ, dukkhanirodhaṁ ariyasaccaṁ, dukkhanirodhagāminī paṭipadā ariyasaccaṁ.

"Four noble truths: the noble truth of suffering, the noble truth of the origin of suffering, the noble truth of the cessation of suffering, the noble truth of the path leading to the cessation of suffering."
Analysis
The Abhidhamma analysis of sacca translates the sutta descriptions of the four truths into the formal categories of dhamma analysis. (Vibh 4)
Dukkhasacca (The Truth of Suffering)
While the suttas list various types of suffering (birth, aging, etc.), the Vibhaṅga's Abhidhamma analysis focuses on the five aggregates of clinging (upādānakkhandha) as the ultimate summary of what suffering is. Any conditioned event that can be clung to is ultimately dukkha. (Vibh 4)
Samudayasacca (The Truth of Origin)
The origin is defined as craving (taṇhā). The Vibhaṅga analyzes craving in its three forms: sensual craving (kāma-taṇhā), craving for existence (bhava-taṇhā), and craving for non-existence (vibhava-taṇhā). (Vibh 4)
Nirodhasacca (The Truth of Cessation)
Cessation is the total fading away and cessation of that same craving. In the Abhidhamma system, this refers to the unconditioned element, nibbana. (Vibh 4)
Maggasacca (The Truth of the Path)
The path is the noble eightfold path, consisting of eight mental factors (cetasika) that, when arising together in a supramundane consciousness, effect the cessation of suffering. (Vibh 4)
Textual notes
- The Saccavibhaṅga is notable for its detailed Suttantabhājanīya which preserves the classic definitions from the Dhammacakkappavattana Sutta, alongside the technical Abhidhammabhājanīya.
- The Abhidhamma emphasizes that these are "noble" truths because they are realized by the noble ones (ariya) and because their realization leads to noble status.
