The nature of the soul /self is like Deep sleep
The waking or dream is the world of objects. And waking and dream is an object to the soul, which is the subject. Without the knowledge of the subject the object will remain as reality. Once one becomes aware of the subject the reality of the object cease to exist as reality.
The knowledge of object [body] as subject is cause of the ignorance. Thus it is necessary to examine the nature of the object in order to realize the fact that the object is not the subject.
The subject is not the form but it is formless. The knower of the object is the subject, which is consciousness. So, the object has no existence without the subject. Therefore it is erroneous view and judge, the truth on the base of object as subject.
Conscious ignorance of all objects [three states] means really the positive knowledge of the soul/ self, which pervades everywhere and everything in the object. Consequently, the ignorance of the ordinary man in deep sleep is really the knowledge of his own self, which is happiness and Consciousness.
One can say about his deep sleep experience only when waking takes place that is in the states of ignorance.
The ignorance of the mind [universe] in deep sleep is nothing but the knowledge of the self, which is nondual peace. Thus the experience in deep sleep, if properly understood, is only one; and that is the soul, which is in the form of consciousness. There is only one there; and hence the ignorance of the many is no experience at all.
