Sages and seers in ancient times who spoke of the spiritual side of nature, gained their insight by moving beyond the confines of the rational physical world. In a similar way to the principles of Godel's theorem, the ancient mystics gained access by deep meditation to a perspective beyond the physical, in order to attain a more complete picture of the physical realm.
In other words, when we are within the illusion of physical reality it is not possible using its own internal methods and concepts to fully understand it. By accessing or looking from a higher level of awareness beyond the boundaries of the "physical illusion', we escape the constraints imposed on us by the finite physical world. To a rational scientific person this may all sound like something out of a science fiction novel. But remember that I stated earlier in the book that unless we can relate physically to our ideas, they are not reality for us.
At this point I would like to introduce what in my opinion is a kind of "unified field theory'. This is what Einstein searched for in vain. The reason for Einstein's failure, is that access to it is beyond mathematics, test tubes and intellectual activity. The intellect can merely confirm its operation.
This theory cannot be accessed with the rational mind, although the rational mind can observe and confirm its operation. The "Param Chaitanya' or all pervading power which exists throughout the universe is the elusive "unified field' for which Einstein searched in vain. It encompasses all of the physical cosmos, and also the realm of the spiritual or Virata in Eastern tradition. Its basic units of propagation (in simplistic terms) are what can be called "vibrations'. At last mankind is at the point of conscious interface between the physical and spiritual. This interface is entered without effort or thought, it is spontaneous and natural. It can be felt via the central nervous system as a physical sensation, it is an actualisation, not something imagined as a theory or concept
