One of the most intellectually challenging books I've ever read. This book brings into light the facts that we already know but we don't know we know. It is a dark book infact, but in the end you'll get to know how to stand upto yourself to face life as a challenge, looking forward without backing down. As far as I think this is essential as mentioned in this book, to alleviate suffering and to keep moving forward, shouldering the burden of being.
