Until the scientists become the seeker of the truth of their existence, the truth will not reveal. The truth of the whole cannot be got under the microscope. When all their invention fails to yield truth they have to use their reason to reach the ultimate core of their existence.
The man who possesses the highest intellect can grasp Advaita, by merely hearing the truth mentioned will know it.
Bhagavad Gita: ~ Reason as means to reality. (Chap.18 verse 37)
In chap. 10 of in Bhagavad Gita, Krishna says: ~ I cannot save you, but I can give you Buddhi (reason). (chap. 10)
In chap. 10 of in Bhagavad Gita, Krishna says: ~ "I have given you the most secret teaching, now reflect over it all" Krishna plainly says reflect, think. (Verse 63 of Chap. 18)
Mundaka Upanishad says: ~ Both states are harmful and take you away from the path of inquiry into truth. (Page 234)
Ashtavakra Gita: ~ It is not the absence of Buddhi (Reason) that can grasp Advaita but the man who possesses the highest intellect. Brains are necessary. Such a man, by merely hearing the truth mentioned will know it. (Page~ 224).
The ‘Self-inquiry’ is finding out the ‘Self’ which is hidden within the world, in which we exist. By inquiring ‘Who am I?’, the ignorance will not vanish. Without getting rid of the ignorance, the Advaitic wisdom will not dawn. Without the Advaitic wisdom, it is not possible to realize the truth, which is hidden within the world in which we exist.
That is why Sage Sri Sankara Says: ~ VC-63. Without causing the objective universe to vanish and without knowing the truth of the ‘Self’ how is one to achieve Liberation by the mere utterance of the word Brahman? — It would result merely in an effort of speech.
What is the use of saying ‘I AM THAT’ without knowing what the ‘Self’ is in actuality. Without knowing the truth of the Self, without realizing the truth of the world in which you exist it is impossible to realize the truth beyond the form, time, and space. By a mere utterance of the word ‘I AM THAT', the truth will not be revealed.
