[481] A phenomenon accompanied by rapture (pītisahagato dhammo) is a condition, by way of root condition (hetu-paccaya), for a phenomenon accompanied by rapture. Roots (hetū) accompanied by rapture are a condition, by way of root condition, for the associated aggregates (sampayuttakā khandhā). At the moment of rebirth-linking (paṭisandhikkhaṇe), roots accompanied by rapture are a condition, by way of root condition, for the associated aggregates.
