Bible is the best in that area. But in others, man it seems like most books that I am presently reading is the best one I have read.
Tolkien's Lord of the Rings trilogy really gave me ecstatic literature explosion when I read it back in my teen years.
You know that it is very subjective question right. So, all the books which I had read in my little life is nearly 100. And the best book from my list is "The Rudest Book Ever" by Shewatabh Gangawar.
It was literally life-changing for me.
