Manduka Upanishad shows how one opinion may be used to contradict another, so that both may be thrown away.+

The essential message of Manduka Upanishad is that the whole world, whatever is seen is only imagined. points out that even though it is harder for them, still women can attain Brahman just as men. Page 351

"From their notion": Everybody has his own imagination about facts and starts from that, instead of discarding his personal idea and looking at the facts. Page 333. V. 83 

Manduka Upanishad shows how one opinion may be used to contradict another, so that both may be thrown away. Opinions are not for philosophy; they are as Ashtavakra says, merely thoughts; it wants the truth.

Opinions belong to scholasticism, not to ultimate truth or Brahman. Ultimate truth or Brahman has no use for opinions.

Manduka Upanishad:~ Those that want ultimate truth Brahman will not practice control of the mind. (p.231)

Manduka Upanishad:~ Yoga is in the sphere of duality and is unnecessary to one who knows non-duality.The eye cannot see it; the mind cannot grasp it. The deathless Self has neither caste nor race, Neither eyes nor ears nor hands nor feet. Sages say this Self is infinite in the great And in the small, everlasting and changeless, The source of life.

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.”

Mundaka Upanishad 3:2:3:- “The weak and timid cannot realize the Self. Self-realization is not possible through intellect or hearing spiritual discourse. One who welcomes God in every activity, through a thorough controlled, and disciplined life, to him also the Soul is revealed

Manduka Upanishad has no assumptions whatever. It is an honest and bold inquiry into truth. It rises above scripture.

Manduka Upanishad:~ Reality and illusion together make Brahman: nothing can be left out.

 Manduka Upanishad:~Only a few will be able to understand and assimilate it 

Manduka Upanishad is not meant for all, as it is based entirely on reasoning.

Look into the nature of the universe. And you will be able to see that the universe by its very nature is illusory. The moment you understand that the universe is illusory, ignorance disappears and Self-awareness arises.

Self-awareness is the state of non-dual reality. That is the state of Advaita. 

Manduka Upanishad:~ All indeed is, this Brahman. This Atman is Brahman (God in truth). (verse-2)

While Brahman lies behind the sum total of the objective universe, some human minds boggle at any attempt to explain it with only the tools provided by reason. Brahman is beyond the senses, beyond the mind, beyond intelligence, beyond imagination. Indeed, the highest idea is that Brahman is beyond both existence and non-existence, transcending and including time, causation, and space, and thus can never be known in the same material sense as one traditionally 'understands' a given concept or object.

Imagine a person who is blind from birth and has not seen anything. Is it possible for us to explain to him the meaning of the color red? Is any amount of thinking or reasoning on his part ever going to make him understand the sensation of the color red? Similarly, the idea of Brahman cannot be explained or understood through material reasoning or any form of human communication. Brahman is like the color red; those who can sense it cannot explain or argue with those who have never sensed it.

Chandogya Upanishad: - One who meditates upon and realizes the 'Self' discovers that everything in the cosmos-- energy and space, fire and water, name and form, birth and death, mind and will, word and deed, mantram and meditation--all come from the Self.

To realize the ultimate truth or Brahman is the prime goal. All the scriptures indicate that Atman is Brahman, and Brahman is the ultimate truth. Therefore the Soul, which is in the form of consciousness, is the ultimate truth. Thus, to realize the ultimate truth is the prime goal. :~Santthosh Kumaar
