Concepts II - It makes something known

Question: When there is seeing through the eyes and we know that it is a pen, it shows that we know the word pen through the mind-door. Is that right?
Sujin: Before we can think of the word pen, we already know a concept. A pannatti is not merely sadda pannatti (a concept of sound) a word or name.
Question: After seeing I remember what was seen. Is the object then already a concept?
Sujin: The Pali term pannatti means: it makes something known (derived from pannapeti).
Question: Must each of the sense-door processes be followed by a mind-door process so that the meaning of things can be known?
Sujin: The five sense objects which are visible object, sound, odour, flavour, and tangible object appear through two door-ways. Thus, visible object appears through the eye-door and then, after there have been bhavanga-cittas in between, it appears through the mind- door. In the same way, sound, odour, flavour, and tangible object appear through the corresponding sense-doors and then through the mind-door.
