Those who lack the intelligence to discriminate between formless witness (subject) and three states (object) will not be able to grasp what is real and what is unreal. Both subject and object are consciousness, not subject alone. 

The truth can never change. The nature of truth is, it can never be changed under any circumstances. It may be misrepresented. It must apply to the whole of existence, to the whole of the universe. It is in the object (three states) alone that one has all changes, as deeper analysis points out.

The subject (formless witness) remains unchanged. The subject (formless witness), as such remains immortal. It can never die for it never changes. The body and world are an object, and goes, but the subject or knower of the body and the universe, can never go. Seeker has to take this principle as his guiding thread and non-dual truth becomes easy to grasp. The formless witness can never be subject to the changes of the object; it is unchanged. The mistake usually made is that subject becomes object, or that object is subject. 

If one wants to have absence of contradictions, absence of duality, there must be one entity, one being. If one has experience which is an object (mind), there is contradiction between subject and object, for "mind” is an object. 

The duality is reality on the standpoint of the false self (ego or waking entity). The duality is mere mirage on the base of the true self, which is formless consciousness. This understanding comes only to the serious seeker, who has real urge to know the ultimate truth, which is beyond the all the teachings and teachers. There is neither teaching, nor teacher, nor student in the realm of truth. –FORMLESS PATH
