Consciousness is ultimate truth or Brahman

Consciousness is ultimate truth or Brahman. Consciousness alone is real. The universe is unreal. Everything other than consciousness is unreal. 

The waking objects fall into two categories- practical life within the practical world waking objects become unreal on the dawn of nondual wisdom. The egocentric knowledge within the practical life is not self-knowledge. Self-knowledge means the means the knowledge of the soul, which is the innermost self. The soul is in the form of consciousness. Therefore, formless consciousness is the innermost self. Thus basing the reason on the soul is soulcentric inquiry. 

Waking objects exist even before they are known. They are product of ignorance. Thus they are covered by ignorance. When this ignorance is removed through wisdom than the duality ceases. The ignorance covers the pure consciousness, which is the innermost self, limited by the object. The object itself is not self-luminous and so no covering is necessary for it to remain unknown. The consciousness limited by the object is self-luminous and so it remains unknown only because of the covering of ignorance. When the covering is removed through wisdom, the consciousness underlying the object illumines the object and then the object is become conscious of. –FORMLESS PATH
