Thank you, Mr TBT
If you read ‘Why I am not a christian‘ by Bertrand Russel’ he makes A compelling point that many unknown things unexplained and somehow used to justify a God’s action cease their appeal when the phenomena is later explained. I thought not much is known about dark matter yet. They are just models for now. We cannot conclude much from examples and they are not proofs
Point 3 comes under the domain of psychology. Sakshi is not needed for such a conclusion. This evolution idea is problematic when one considers the sutra Tat Tvam ASI which is unconditional.
Sure, there will be always unexplained things in the Universe. But the point was 'observer driving evolution' is a common phenomena and I explained it with an example of dark matter bending space to kick-start gravitational heating. Pretty much similar things happen when a catalyst drives a chemical reaction or an enzyme drives biological evolution or even when neutron masses contribute to atomic interactions.
“sa ya eSo aNima aitad AtmyaM idaM sarvam tat satyam sa Atma tat tvam asi Svetaketu”
That which minuteness, that 'self', the satyam (existence), that Atman - that is in you Svetaketu'.
Uddalaka explains it with salt dissolved in water. One can't separate that taste of salt in water without giving up the form of water (evaporation). That Atman is present in you as that minuteness says Uddalaka.
The saltiness has become the sAksi or observer of water. Characteristics of water is changed because of the saltiness and that saltiness will remain in the water whether we drink a drop or cup, as an unchanging witness to all that happens to water, while remaining inside it ever.
In chandogya upanishad it is further explained with an example of a story of dying man. You ask the dying man, do u recognize me..? His manas guides the prAnA, prAnA guides the organs and they work together. he responds yes yes. But that Atman is present in his manas as salt dissolved in water. At some point of time, this salt evaporates out of the water or Atman settles down like a cream of butter dissolves into curd that is not stirred. The manas no longer remains what it is without that Atman and it can't guide the prAnA and hence the organs. We say person has died.
This Atman is the sAksi. Why do we call that a sAksi or observer..? There is another story for it in Chandogya Upanishad.
Someone is kidnapped blindfolded from gAndhAra nation. He is left out somewhere and has to return to gAndhAra. How does he return back..? He uses prchhan (enquiry) to ask people the way back, medhavi (judgement) to decide if what they are saying is right and panditam (third party expertise) of people who seem to know the way better than others. All three are observers, outside, unconnected to him.
We are born like this, blindfolded, kidnapped from somewhere. As we grow up we use prcchan (enquiry) to understand where we are, medhavi (judgement) to understand which is the right way to grow and go back to where we came from. This is possible only when we have a detached observer or witness inside us,(sAksi) who guides us like third party observers of the previous story. This is our detached observing manas-sAksi in us. Then we have external people with expertise (panditam) who can guide us totally detached in this pursuit. They are the 'guru'. The ultimate guru is our manas-sAksi.
Just some ramblings.. that's all...
