Hi everyone,
Take the example of a String. It is supposed to be the smallest part of what we are and everything else is. If the atom is as big as the solar system, the String is said to be as big as a tree. It is so small that no one can hope to see or even know what it is. It is probably some form of energy wriggling around like a rubber band.
This String is believed to vibrate in 11 dimensions to generate various elementary particles which then form more complex particles like protons, particles then form atoms of elements, which form compounds, which then form cells and organisms, which then form humans and others. The String is the most fundamental aspect of Nature that we currently are able to theorize. The String is the only thing that really exists, everything else is only its transformation and an illusion. If it stops vibrating, the universe could simply disappear in a jiffy.
Imagine the String is conscious, what will it be aware of? Will it think of itself as a human or as a bacteria or as a hydrocarbon or as an atom or as an electron or quark? Or will it think of itself as a String?
We can imagine its Consciousness projecting itself into all its physical transformations. It will be conscious as a human, as a bacteria, as an atom, as an electron and also as itself. Its consciousness will be different at different levels.
The idea of the soul or Self is similar, philosophically.
Cheers.
Sriram
