If only the whole world not only read this book but understood it and applied it, surely we'd be living in a higher state of collective conscious. Or at the least we'd be off to a good start. I attempted this book at around age 25 but I was way too green for it then. Now at 31 after making lifestyle changes such as clean eating the way nature intended, along with meditation - I absolutely appreciate this book and it resonates significantly. Don't be intimidated by it, research each principle or topic independently in different form if you don't fully understand it, such as a documentary.
