Sage Goudapad:~Duality is for the unwise, non-duality and undifferentiated Reality is for the wise and difficult to grasp.

The essential message of Manduka Upanishad is that the whole world, that 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 fact. 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.

Your opinion is based on the dualistic perspective is based on the false Self (ego or you) within the false experience.

Gnanis judgment is based on the non-dualistic perspective based on the Soul, the  Self.

Whatever one sees in this world is not real. When you realize the ‘Self’ is not 'you, but the ‘Self is the Soul, then you realize the world in which you exist is merely an illusion created out of the Soul, is present in the form of consciousness.

The Self is not you because you are bound by the experience of birth, life, death, and the world. From the standpoint of the Soul, the innermost Self, the world in which you exist is merely an illusion.

The experience of birth, life, death, and the world is nothing to do with the Soul the innermost Self. When you are not the Self, you cannot relate the Self with your experience of birth, life, death, and the world because the Soul, the Self is birthless and deathless because it is ever nondual.

When the Soul wakes up with its own awareness, then you and your experience of the world becomes unreal the same way as the dream becomes unreal when waking takes place.

If you imagine within the dream it becomes unreal when waking takes place. Your imagination within the dream remains a reality till waking takes place. The same way your imagination within the waking remains a reality till wisdom dawns. Wisdom dawns when you realize you are not the Self but the Self is the  Soul, which is present in the form of consciousness. 

If you are not the Self then your imagination has no value because you are the false self within the illusion (waking).

When the Self is not you then what is the use of dropping the opinion. It is not you who has to drop the opinion but the Soul, the 'Self' has to wake up from the sleep of ignorance. When The Soul, the Self' wakes up then the world in which you exist ceases to exist as a reality.

Just by saying you are already that the wisdom will not dawn. Perfect understanding of ‘what is needed, if one wants to realize the truth, which is beyond the form, time, and space. : ~ Santthosh Kumaar
