Mundaka Upanishad 1:2:8:- “Remaining in the fold of ignorance and thinking “we are extremely wise and learned,” the fools with boastful nature ramble about like the blind led by the blind alone.”
People think that, more they think, the more they will get; but it is really an error. It remains only a thought and gives them back only thoughts. Anything seen, observed, cannot be the Self or the Witness.
Consciousness (soul) is the substance and the witness of the duality. The duality is present in the form of mind. The Mind is present in the form of the universe. The universe appears as waking or dream and diapers as deep sleep. The one which is aware of the coming and going of the three states is neither the waking entity nor the dream entity but the formless soul, which is present in the form of consciousness. When the soul becomes aware of its formless non-dual true nature in the midst of duality it is called self –awareness. It is foolish to limit the consciousness only to duality because the consciousness pervades all the three states
Consciousness is the shoreless Non-dual Ocean. Consciousness is beyond form, time and space. Consciousness is beyond instinct, intellect, imagination and inspiration. It is unconscious of its true nature when it is in illusion. Only beyond illusion it is in its true nature.
All the accumulated knowledge, experiences and understanding based on physical self (ego or waking entity) are falsehood based on the false self, within the false experience (waking). Thus, whatever is based on the waking entity is bound to be falsehood because waking experience itself is false hood. Since many teachers and teachings are based on the false self (ego or body as Self) and they consider the false experience (three states) as reality, they are incapable of grasping the witness, which is within the three states, but it is without the three states.
Thus, the formless knower of the three states has to be grasped mentally and realize the fact that, all the three states, which comes and goes, are mental. They are impermanent. The formless witness or knower of the three states is permanent and eternal. Therefore, there is a need to understand “What is Mind?” and “What is the substance of the Mind?” in order to understand and assimilate the non-dual truth.
The Shruti has directly denied manifoldness in Brahman. The non-dual cause being an established fact, how could the phenomenal universe be different from It?
The Shruti has condemned (the belief in variety) in the words, “The person who”, being deceived by Maya, “sees variety in this (Brahman), goes from death to death”.
Inasmuch as all beings are born of Brahman, the supreme Atman, they must be understood to be verily Brahman.
The Shruti has clearly declared that Brahman alone is the substratum of all varieties of names, forms and actions.
For this one has drop all his accumulate knowledge, which he is using as a yardstick and lands himself in pursuit of argument without reaching anywhere. One has to think deeper and analyse and verify everything and accept only un-contradictable truth. Nothing has to be accepted as truth because some great thinker says it or I am saying it.
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 the world are an object, and goes, but the subject or the knower of the body and the universe, can never go. The 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 an absence of contradictions, absence of duality, there must be one entity, one being. If one has experience which is an object (mind), there is a contradiction between subject and object, for "mind” is an object.
Sri Ramana Maharishi Says:- The self is fullness of consciousness. Therefore, there is nothing apart from it.
The duality is reality on the standpoint of the false self (ego or body as Self). The duality is a mere mirage on the base of the true self, which is formless consciousness. This understanding comes only to the serious seeker, who has a 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.
