This book is an outstanding one. As all of us know that Rabindranath Tagore got a noble prize in 1913 for this book. One can read it whenever he/she likes. This is the best book I have ever read and also one of the topmost book in the world ever written. You can get it's english version too which is by Tagore only. Therefore I would request you to read this book at least once in your lifetime.
Gitanjali brings out the soul from within. It strives to portray that this world and humans are filled with a cosmic boon and everyone has to drink it's share from the fountain of life. One has to shed the cloak of self and merge oneself into the ocean of universal self.
The poems are written in simple language with metaphors and ornaments drawn from ordinary life but tinged with divine grace. They are to be felt and not explained.
