At Sāvatthī. Sāvatthiyaṁ viharati.

“Mendicants, diversity of elements gives rise to diversity of contacts. Diversity of contacts doesn’t give rise to diversity of elements. “Dhātunānattaṁ, bhikkhave, paṭicca uppajjati phassanānattaṁ, no phassanānattaṁ paṭicca uppajjati dhātunānattaṁ. And what is the diversity of elements? Katamañca, bhikkhave, dhātunānattaṁ? The eye element, ear element, nose element, tongue element, body element, and mind element. Cakkhudhātu …pe… manodhātu—This is called the diversity of elements. idaṁ vuccati, bhikkhave, dhātunānattaṁ.

And how does diversity of elements give rise to diversity of contacts, while diversity of contacts doesn’t give rise to diversity of elements? Kathañca, bhikkhave, dhātunānattaṁ paṭicca uppajjati phassanānattaṁ, no phassanānattaṁ paṭicca uppajjati dhātunānattaṁ? The eye element gives rise to eye contact. Eye contact doesn’t give rise to the eye element. … Cakkhudhātuṁ, bhikkhave, paṭicca uppajjati cakkhusamphasso, no cakkhusamphassaṁ paṭicca uppajjati cakkhudhātu …pe… The mind element gives rise to mind contact. Mind contact doesn’t give rise to the mind element. manodhātuṁ paṭicca uppajjati manosamphasso, no manosamphassaṁ paṭicca uppajjati manodhātu. That’s how diversity of elements gives rise to diversity of contacts, while diversity of contacts doesn’t give rise to diversity of elements.” Evaṁ kho, bhikkhave, dhātunānattaṁ paṭicca uppajjati phassanānattaṁ, no phassanānattaṁ paṭicca uppajjati dhātunānattan”ti.

Tatiyaṁ.
