Shoyoroku - Case 11: Unmon's "Two Diseases"

Great Master Unmon said,
  "When the light does not penetrate, there are two diseases. Everything is
   unclear and things hang before you: this is one disease. Even after you
   have realized the emptiness of all things, somehow you feel as if there were
   still something there. This shows that the light has not yet penetrated
   thoroughly.
   Also there are two diseases concerning the Dharma-body. You have reached the
   Dharma-body, but you remain attached to the Dharma and cannot extinguish your
   own view; therefore you lead a corrupt life around the Dharma-body: this is
   one disease. Suppose you have truly penetrated to the end, if you give up
   further efforts, it will not do. You examine yourself minutely and say you
   have no flaw: this is nothing but a disease."
