[326] A derived phenomenon (upādā dhamma) is a condition for a non-derived phenomenon (no-upādā dhamma) by prenascence condition (purejāta-paccaya): object-prenascence (ārammaṇa-purejāta) and base-prenascence (vatthu-purejāta).
Object-prenascence: [one contemplates] the eye … the base (vatthu) as impermanent … grief arises. One sees a form with the divine eye (dibba-cakkhu); one hears a sound with the divine ear element (dibbā sotadhātu). The form base (rūpāyatana) [is a condition] for eye-consciousness (cakkhuviññāṇa), the taste base (rasāyatana) for tongue-consciousness (jivhāviññāṇa).
Base-prenascence: the eye base (cakkhāyatana) [is a condition] for eye-consciousness; the body base (kāyāyatana) … the base is a condition for the aggregates (khandha) that are non-derived by prenascence condition.
A non-derived phenomenon is a condition for a non-derived phenomenon by prenascence condition: object-prenascence: [one contemplates] tangible objects as impermanent … grief arises. The tangible-object base (phoṭṭhabbāyatana) is a condition for body-consciousness (kāyaviññāṇa) by prenascence condition.
Derived and non-derived phenomena are a condition for a non-derived phenomenon by prenascence condition: object-prenascence and base-prenascence. The tangible-object base and the base are a condition for the non-derived aggregates by prenascence condition; the tangible-object base and the body base are a condition for body-consciousness by prenascence condition.
