"Vimalakirti Sutra" establishes the theme that the whole world is founded on non-being. This is, in fact, the thought of the Prajna School to show that both subjects and objects are "sunya" (without being nor metaphysical essence). Through the methodology of single negation and dualistic negation, it clears all attachments. To eliminate only the bad effects of things instead of excluding all things from the world, it maintains all logical possibilities of re-confirming the world for assisting enlightenment. Enlightenment cannot be described by languages and the As-suchess transcends the whole linguistic world, therefore, Vimalakirti could only keep silent in order to get in the non-dualistic real world.
