Thought and thinker are reality within the universe. The thinker and the thought exist within the universe. The man and his experience of the universe is a reality within the waking experience. The waking experience is mere illusion on the ultimate standpoint. Therefore, the individual experiences are part of the illusion. Thus thought, the thinker and the world are part of the illusion. The self is ever that which is aware of the thought, thinker and world together without physical apparatus. The thoughts will not rise without the form whereas the self is formless. Thus Self-knowledge or Brahma Gnana or Atma Gnana is necessary to know what is what.
Positive and negative thoughts and the thinker are made of the same material. Whether one thinks rightly or wrongly he is thinking as a person. The thoughts will not rise without the form. Without the form there are neither thoughts nor the thinker. This positive or negative thinking or right or wrong thinking is part of the physical existence and nothing to do with ultimate truth. Experience is prior to thought. Only in waking or dream one gets thought. Therefore one has to mentally trace the source of the waking or dream experience in order to realize the waking experience is as unreal as a dream. When waking experience itself is than the waking entity and its thoughts are part and parcel of that illusion. Self-awareness arises only when wisdom dawns. Wisdom dawns only when waking entity realizes it itself is not the self.
Only in religion and yogic path one has to follow and practice. Everyone thinks he has to follow some guru or god men. But all these methods are full of frustrations and give no real satisfaction. Reality has no method. Illusion has many methods, many problems and many concepts. To overcome illusion, or concepts, one should know the source of the mind and from where does this mind arise? “When the mind is there the universe is there. Absence of mind absent of the universe. Absent of the Universe is absent of duality. Absent of duality is absent of thoughts. Thus until one becomes aware of what is the mind and what is the substance of the mind it is impossible to assimilate the nondualistic or Advaitic truth.
To know the nondual Reality, deeper thinking is required. The thinking faculty ceases and becomes still when it reaches the source of the mind. One has to realize the waking entity is false self within the false experience from the ultimate standpoinWhere there is no experience then there is no duality where there no duality then there is no second thing exist other than the self-awareness. Therefore seeker has indulge in deeper self-search and trace and overcome the obstacles. For the sincere and serious seekers the inner grace will guide until the ignorance vanishes and he becomes aware of the fact that the diversity [universe or Illusion] is a mere mirage created out of consciousness [Atman].
Waking experience in which a person perceives the world doesn't exist as real in reality because, everything is consciousness, and apart from consciousness there is nothing in the waking experience.
Whatever is thought of within the waking experience makes Him something other than what He is. When the waking experience ends, what happens? It is consciousness alone prevails without the three states.
