The Abhidharmakośakārikā approach is Vasubandhu's Abhidharma commentary text in the Sarvāstivāda school (c. 500 CE). It has four intricate causal conditioning constructions with the: 1) root cause, 2) immediate antecedent, 3) object support, and 4) predominance. Then, the six causes are: 1) instrumentality (kāraṇahetu), deemed the primary factor in result production; 2) simultaneity or coexistence, which connects phenomena that arise simultaneously; 3) homogeneity, explaining the homogenous flow that evokes phenomena continuity; 4) association, which operates only between mental factors and explains why consciousness appears as assemblages to mental factors; 5) dominance, which forms one's habitual cognitive and behaviorist dispositions; and 6) fruition, referring to whatever is the actively wholesome or unwholesome result. The four conditions and six causes interact with each other in explaining phenomenal experience: for instance, each conscious moment acts both as the homogenous cause, as well as the immediate antecedent consciousness condition rise, and its concomitants, in a subsequent moment.
