Points of Controversy
5.3. Of Perverted Perception or Hallucination (in jhāna)
Theravādin: If your proposition is right, then do you imply that this “perversion” is the same as that involved in seeing the permanent in the impermanent, happiness in Suffering, a soul in what is not soul, the beautiful in the ugly? Of course you deny.
You admit that the reversal of judgment which sees permanence in impermanence is a bad judgment, and those other judgments above-stated also. Yet you will not admit that cognition during jhāna is badly accomplished.
If it were an Arahant who so accomplished jhāna, would you claim a perverted cognition for him? You could not. Or, if you could, you would have to make him liable to reversals of perception, consciousness, and views in general.
You say that the earth is actually there, and that in entering jhāna by the consciousness of earth as earth, perception is perverted. Substitute for earth Nibbāna: would you still say that perception was perverted?…
