Grammatical Analysis
Sampayuttapaccaya: [m.] Association condition. Formed by sampayutta (associated, perfectly combined, conjoined) + paccaya (condition).
Orthodox Definition
Sampayutta-paccaya is the nineteenth of the 24 Conditions. It applies strictly and exclusively to mental phenomena (nāma). It is a highly specialized refinement of the Co-nascence condition (Sahajāta-paccaya).
When consciousness (citta) and mental factors (cetasikas) arise, they do not merely exist side-by-side; they blend into a single, indivisible cognitive unit. They share four characteristics: they arise together, they perish together, they take the exact same object, and they rely on the exact same physical sense base.
Because they blend so perfectly, one cannot separate the feeling of pleasure from the consciousness experiencing it. The commentaries famously compare Sampayutta-paccaya to the mixing of water and milk; once mixed, they are indistinguishable and completely unified.
