A completely mind-blowing dose of non-fiction. Although dated, I cannot find anything more modern online or otherwise that refutes his reasoning. That said, this book involves a lot of reasoning that would be difficult, if not impossible, to support factually. Well grounded though, I can't wait to see how deep he can go...

...finally finished this work. I won't attempt to summarize the depth of what is covered in this book. I will only say that if you are a "thinker", constantly searching for mor

Here you will find the mind of the 19th and 20th century philisopher/ Realizers like Ralph Waldo Emerson & Richard Bucke.

Peter D. Ouspensky (March 4, 1878–October 2, 1947), (Pyotr Demianovich Ouspenskii)a Russian philosopher,who invoked euclidean and non-euclidean geometry in his discussions of psychology and higher dimensions of existence. His first book, The Fourth Dimension, appeared in 1909; his second book, Tertium Organum, in 1912; and A New Model of the Universe in 1931. This last wo

Another book I've had on my shelf for decades. Uses mathematics (Warning! high level math, in case you're numbers-challenged) to prove the existence of God!!

I can sum up my impression of this book by quoting a sentence from it: "And truth itself is motion, and can never lead to arrestment, to the cessation of search."

This book, written in 1920, is timeless. It compels the reader to question, to disagree, to pursue. It is also a tool for measuring one's understanding of new concepts...opening the door for something more. I first read this book about 20 years ago, and I am amazed by my growth in consciousness, in awareness. What appeared obscure, the

How many times will I allow a Russian Theosophist to break my heart?

I followed his paces so faithfully! He measured his stride so! He spoke to me of his affairs with Kant and with Consciousness.

Awesome book. Never knew that the beyond can be deduced from philosophy and logic, and that too in such a beautiful manner. And the application of maths was just wow. Ouspensky used analogies very nicely. This book introduced me in much details to the world of beyond world

Excellent, Excellent book!

It was the most exciting riveting and analytically challenging book I have ever read.....

I get excited just remembering back when I did read it- even though I did get a headache., I loved it!!!

Be very careful with this book. It will take you into a dangerous labyrinth that if you do not take precautions will trap you. He presents a grand problem, The Kantian Problem, but then takes a very wrong road to its resolution.

This book opened my mind like a crowbar opening a locked lid. It took lots of pressure but the sudden snap as my mind finally opened has changed my view of life, the world and the universe.

Came upon this treasure while reading a short story titled, "My Shoe" by a very witty and insatiable writer William Saroyan. Will provide a review upon completion of it.

I think this is the best book which analysed vedanta philosophy of shankaracharya through pure logic.
