[1119] A phenomenon (dhamma) that leads neither to accumulation (ācaya) nor to dispersal (apacaya) is a condition, by decisive-support condition (upanissaya-paccaya), for a phenomenon that leads neither to accumulation nor to dispersal: object decisive-support (ārammaṇūpanissaya), proximity decisive-support (anantarūpanissaya), natural decisive-support (pakatūpanissaya).
Natural decisive-support: In dependence on bodily pleasure (kāyika sukha), one mortifies oneself, torments oneself, and experiences suffering (dukkha) rooted in the quest. In dependence on bodily pain (kāyika dukkha) … season (utu) … food (bhojana) … lodging (senāsana), one mortifies oneself, torments oneself.
Bodily pleasure … bodily pain … season … food … lodging is a condition, by decisive-support condition, for bodily pleasure, for bodily pain, and for the attainment of fruition (phalasamāpatti).
An Arahant, in dependence on bodily pleasure, the unarisen functional attainment (kiriyasamāpatti) … contemplates with insight. In dependence on bodily pain … season … food … lodging … he contemplates with insight.
