Gitanjali book written by Rabindranath Tagore is very best book for a deep reader.
This having a deep knowledge of the author.
I went through this book, I feel pleasant and full of knowledge.
I insists to those reader who really want to spent a valueable time with something really valuable just go through this book
The way of writing, the way of thinking, the way of explaining is brilliant of Rabindranath Tagore.
