Study On The Ninth Consciousness Theory And The Mind-nature Meditation Of Mahqyqnasagraha School

This paper researches the ninth consciousness theory and the mind-nature meditation of Mahqyqnasagraha School.As them are theoretical principle and the theoretical characteristic of Vijnapti-matrata theory, explores basic viewpoints of Mahqyqnasagraha School and brings to light its theoretical defects as well as its ultimate destination by comparing with Yogacarabhumi-sastra School.There are two points to explain of the ninth consciousness theory. Fristly, Is Asta-vijnanani defilement or purity (Klesa-Samklesa-Vyavadana染净)?How are other seven consciousness between with it? For analysing relationship of these consciousness clearly, have them saw in scope with Five-dharmas, Three-nature and Two forms of selflessness. All of them made up a tradition in Vijnapti-matrata theory. Secondly,advocated Amala-vijnana as Tathagatagarbha,original purity mind,The truth nature, "combining consciousness of Prajna and Tathagatagarbha(正智与真如)".It forces Asta-vijnanani to turn, in additions to this,It's the living mood of other consciousness and the truth of Vijnapti-matrata theory in which both mood and consciousness are disappeared. In common mood, Asta-vijnanani with Amala-vijnana both are, then leading to a falsity and a truth consciousness are together which were respectively. But Amala-vijnana isn't real consciousness, so mission is inexsitence.The mind-nature meditation of Mahqyqnasagraha School, insist on mind original purity of Vijnapti-matrata theory.The nature of consciousness are purity for being apart with klesa,but very opposite defilement of its samuda∧ca∧ra(performing sight),as being anvita(together).So eight consciousness are purity in nature. Amala-vijnana is confused with defilements in common mood, till these dusts break off, Amala-vijnana will return into which it should be. So mind-nature is original purity.
