What word is the closest to qualia I think I get what qualia means, intuitively at least:


  Feelings and experiences vary widely. For example, I run my fingers
  over sandpaper, smell a skunk, feel a sharp pain in my finger, seem to
  see bright purple, become extremely angry. In each of these cases, I
  am the subject of a mental state with a very distinctive subjective
  character. There is something it is like for me to undergo each state,
  some phenomenology that it has. Philosophers often use the term
  ‘qualia’ (singular ‘quale’) to refer to the introspectively
  accessible, phenomenal aspects of our mental lives.


In Buddhism what is the word for this "introspectively accessible" aspect of "what it is like"?

Is the term just "phenomena" or is there some other more subtle translation, like "awareness"?
I don't think there is any single word that's cleanly equivalent to qualia, but there are some that approach the idea from different angles.


  sabhāva-dhamma: Condition of nature; any phenomenon, event, property, or quality as experienced in and of itself.


sabhāva by itself means "own-being" or "own-becoming". It describes the intrinsic nature or essence of living beings.


  dhamma: (1) Event; a phenomenon in and of itself; (2) mental quality; (3) doctrine, teaching; (4) nibbāna. Also, principles of behavior that human beings ought to follow so as to fit in with the right natural order of things; qualities of mind they should develop so as to realize the inherent quality of the mind in and of itself.


dhamma by itself can describe a kind of mental quality or quality of thought.


  mūla: Literally, "root." The fundamental conditions in the mind that determine the moral quality — skillful (kusala) or unskillful (akusala) — of one's intentional actions (see kamma). The three unskillful roots are lobha (greed), dosa (aversion), and moha (delusion); the skillful roots are their opposites. See kilesa (defilements).


mūla describes the root of our actions; the quality of our intention behind them.

sabhāva-dhamma and dhamma probably come closest, while mūla carries the same concept but applies it very specifically to the mental root of action.
