Hekiganroku - Case 84: Vimalakirti and "Not-Two"

Vimalakirti asked Manjusri,
  "What does it mean that the Bodhisattva enters the Dharma-gate of Not-Two?"
Manjusri said,
  "I see it like this: in all phenomena, there are neither words nor
   explanations, neither presentations nor knowledge; it is beyond all
   questions and answers. That is what I understand with 'to enter the
   Dharma-gate of Not-Two'." ....
Then Manjusri asked Vimalakirti,
  "All of us have finished giving our explanations. Now you should give your
   explanation. What does it mean that the Bodhisattva enters the 
   Dharma-gate of Not-Two?"

 (Setcho said, "What did Vimalakirti say?" Again he said, "Seen through!")
