Arthaviniścayasūtram 4. The Twelve Sense-Spheres

Herein, monastics, what are the twelve sense-spheres?

They are as follows:

   The internal eye sense-sphere,
   the external visible-form sense-sphere,
   the internal ear sense-sphere,
   the external sound sense-sphere,
   the internal nose sense-sphere,
   the external smell sense-sphere,
   the internal tongue sense-sphere,
   the external taste sense-sphere,
   the internal body sense-sphere,
   the external tangible sense-sphere,
   the internal mind sense-sphere,
   the external thought sense-sphere.

These, monastics, are said to be the twelve sense-spheres.
