This book is one of the greatest works of the 20th century.
As a person who was highly scientific and possessed a clear understanding of Einstein's Theory of Relativity and of Quantum Theory, the conventional ideas of God as presented in western and some eastern religions could not satisfy me.
I had started to think that I would never really believe in an Intelligent God, just impersonal "intelligent nature". Until I read this book.
Like Albert Einstein, I was bothered by the existence of the Cosmos itself: why it should be here at all.
This book gave me the answer to my deepest and most troubling questions about God and the world. Now I understand clearly why the laws of the Universe are the way they are: Intricate and intelligent.
After reading and truly assimilating the ideas in Paul Brunton's book, I now know why matter and energy has to be one entity as proven by Einstein's Relativity Theory. I also now understand why the Uncertainty Principle of Quantum Theory has to be the way it is.
This book clearly shows how everything has to be an expression of One All-Encompassing Principle (God) that is inherently intelligent, but not God as the arbitrary creator in Geneses in the Bible.
It shows how the cosmos is not a huge material thing, as formerly thought of in nineteenth century Newtonian physics but is really a vast, dynamic, mental expression existing in a Cosmic Mind.
I'm a scientifically minded person to whom God has become real and experience able, thanks to this book. If you have covered the prerequisites: some advances in meditation, and have intelligently questioned the nature of matter and reality, then you are ready to read this book.
