Awareness of the senses contacting an object.

There are two types of perceptions: external and internal.

  • External perception is awareness of a sense contacting a gross material object, e.g.
    • the ear hears a call or the eye sees a flame.
  • Internal perception is awareness of thoughts, emotions, reasons, and so forth, e.g.
    • musing on a distant place, a trill of excitement, a contradiction in logic
