When wisdom dawns one that becomes diversity becomes unity

The Understanding and the one who understood is part of the waking.  Waking also appears and disappears as dream. Thus, the understating on the standpoint of the waking entity /ego is mere accumulation of dross.  Therefore, there is a need understand  the 'self is neither the waking entity nor the self is the dream entity but the self is the formless soul,which is the  witness of the three states,which comes and goes in succession. On the standpoint of the formless witness,  the three states are mere illusion. Thus the experience of  birth,life,death and the world  is mere illusion. 

The memory is based on the waking entity. Waking entity is  false self within the false experience. On the base of  the formless soul, the innermost  self,  the memory is part of the illusion.When the wisdom dawns, then the memory becomes part and parcel of the illusion.  

identifying self as the waking entity, which is the false self, fuels the sense of duality. Duality makes one feel the individuality as reality. Thus, the division /diversity are mere illusion on the standpoint of  the formless soul, the innermost self.   Knowledge of soul or consciousness,the innermost self brings unity in diversity. 

When wisdom dawns one that becomes diversity becomes unity. The duality and non-duality are one in essence.   Therefore,  the diversity(universe)   is mere illusion created out of non-dual material.  Thus the material alone is real and all else is mere illusion . The material is consciousness, the innermost self. 

Therefore,  the existence of the   formless witness of the three states has to be traced and mentally grasped, and then only the perfect understanding is possible. Otherwise one will remain in the grip physical based intellectuality.
