At Sāvatthi.

"Bhikkhus, dependent on the diversity of elements, there arises a diversity of contacts, dependent on the diversity of contacts, there arises a diversity of sensations.

And what is the diversity of elements? The objects of vision, sounds, smells, tastes, physical sensations, and mental objects. This is called the diversity of elements.

And how is it, bhikkhus, that dependent on the diversity of elements, there arises a diversity of contacts, that dependent on the diversity of contacts, there arises a diversity of sensations?

Dependent on the objects of vision, there arises a contact with the eye, dependent on the contact with the eye, there arises a sensation connected with form. Dependent on sounds, there arises a contact with the ear, dependent on the contact with the ear, there arises a sensation connected with sound. Dependent on smells, there arises a contact with the nose, dependent on the contact with the nose, there arises a sensation connected with smell. Dependent on tastes, there arises a contact with the tongue, dependent on the contact with the tongue, there arises a sensation connected with taste. Dependent on physical sensations, there arises a physical contact, dependent on the physical contact, there arises a sensation connected with touch. Dependent on mental objects, there arises a contact with the mind, dependent on the contact with the mind, there arises a sensation connected with mental objects.

Thus, bhikkhus, dependent on the diversity of elements, there arises a diversity of contacts, dependent on the diversity of contacts, there arises a diversity of sensations."
