Some selected quotes from the book:

“Contrariwise,” continued Tweedledee, “if it was so, it might be; and if it were so, it would be; but as it isn’t, it ain’t.  That’s logic.”
–Lewis Carroll, Through the Looking Glass, and What Alice Found There (1871)

“In reality, Heisenberg said, all possibilities simultaneously exist, until a  single one materializes upon observation.”

[Attention students of RHS:]  “[T]he past isn’t something that has already irrevocably occurred.  Rather, long-ago events depend on the present observer.  Until they’re observed at this moment, the events didn’t really unfold, but lurked in a blurry probabilistic state, all ready to become an actual ‘past’ occurrence only upon our current observation.  This astonishing possibility is called retrocausality.”

“I am reality without beginning . . . I have no part in the illusion of ‘I’ and ‘you,’ ‘this’ and ‘that.’  I am . . . one without a second, bliss without end, the unchanging, eternal truth.  I dwell within all beings as . . . the pure consciousness, the ground of all phenomena, internal and external,  I am both the enjoyer and that which is enjoyed.  In the days of my ignorance, I used to think of these as being separate from myself.  Now I know that I am all.”
–Adi Shankara (788 C.E. – 820 C.E.) was a philosopher and theologian from India who consolidated the doctrine of Advaita Vedanta. He is credited with unifying and establishing the main currents of thought in Hinduism. Wikipedia

“I was studying for a physiology test when something in the textbook about the visual part of the brain suddenly gave me a split-second insight that the distinction between ‘external’ and ‘internal’ is unreal.  Then that intellectual insight abruptly changed into something else.  An enormous weight I’d never realized I had borne was suddenly lifted.  An experience began that no words could convey.  It was ineffable and life-altering.  The best I can say is that ‘I’ was suddenly gone, replaced by the certainty of being the entire cosmos.  There was absolute peace.  I knew with total confidence, not logically–because, as I said, Bob was no longer present–that birth and death do not exist.  That all is perfect eternally, that time is unreal, and that all is one.  The joy was beyond anything I could have imagined.  The to-the-marrow certainty could perhaps be better described as a recognition, an ancient familiarity of being Home.”
–co-author Bob Berman describing an experience he had in 2008

“We have known for a century that light is composed of waves of magnetism along with electrical undulations traveling at right angles to it.  Neither magnetism nor electricity have inherent color or brightness, and thus even if there were an independent universe beyond consciousness, it would have to be utterly invisible.  This bears repeating:  At best, any separate external universe must be blank or black.”

“Reality is an active process that always involves our consciousness. Everything we see and experience is a whirl of information occurring in our minds, shaped by algorithms (represented here by digital zeroes and ones) that create brightness, depth and a sense of time and space.  Even in dreams, our mind can assemble information into a 4D spatio-temporal experience.  ‘Here,’ said Emerson, ‘we stand before the secret of the world, there where Being passes into Appearance, and Unity into Variety.'”

“The only things we can ever perceive,” said George Berkeley, for whom the campus and city were named, “are our perceptions.”

“That the universe (taken as a whole) does lie beyond our logic should be obvious, but somehow escapes the notice of cosmology textbooks.  Look at our models:  Many say a Big Bang started it all, but have no idea, not the foggiest, how you get an entire universe of matter/energy out of nothingness.  The very idea makes no sense whatsoever, even if it may sound okay to the majority of people simply because it’s been repeated so often.  (The very term Big Bang was actually coined pejoratively by Fred Hoyle in 1949 as a way to ridicule the notion as preposterous on its very face.)”

“For we convinced physicists, the distinction between past, present, and future is only a stubbornly persistent illusion.”
–Albert Einstein shortly before his death in 1955

“In 2012, a team at the University of California, Berkeley, studied 900,000 galaxies and found that large-scale space shows no sign of warping.  The conclusion?  This flat large-scale topography indicates that the universe is probably infinite, since a finite cosmos would display a curvature in its space-time, caused by the enormous mass of its combined galaxies and dark matter.  This new discovery indicates that the cosmic inventory of galaxies and planets is endless.  In April 2013, Debra Elmegreen, then president of the American Astronomical Society, shrugged it off to one of the authors who’d asked what she made of this news that the visible cosmos is enveloped in an infinitely larger matrix:  “Even if we can only observe a very small fraction of the universe, that’s plenty to keep us busy.”  But she slightly misspoke.  It’s not a very small percentage that’s observable.  You see, any fraction of infinity is zero.  It means we cannot see even a few paintbrush strokes of the celestial masterwork.  Thus, as briefly noted in chapter, 1 all we can ever hope to study is zero percent.  And when a sample size is zero, no conclusions are trustworthy.  Thus this illusion extends to everything we think we know about the  cosmos.”

“‘There is,’ wrote Thoreau, ‘always the possibility . . . of being all.‘  By a conscious effort of the mind, Thoreau made clear that he could stand beside himself, aloof from actions and their consequences; and all things, good and bad, went by him like a torrent.  ‘I may be either the driftwood in the stream, or Indra in the sky looking down on it.’  What is not in doubt even in these early research stages is that the observer is correlative with the cosmos.  That time does not exist.  And perhaps the most cheerful takeaway from biocentrism:  Since there’s no self-existing space-time matrix in which energy can dissipate, it’s impossible for you to ‘go’ anywhere.  In a nutshell, death is illusory.  So far as actual direct experience is concerned, you will continue to find what you’ve always observed:  Consciousness and awareness never began, and will never end.”
