Long time ago I had a chance to made a glimpse over a book called Songs Of Innocence and Song Of Experience. Surprisingly, the copy was the earliest published one and can be consider as a good piece to enrich anyone's collection. The book was written by William Blake with his own paintings for each of the poems he composed for the book.
Songs Of Innocence is filled with utopian bliss where you can find a little girl is asking to lamb; who made him so beautifully. But in the later part of the book where he sang of experience or the cruel world. Here you will find a struggling chimney sweeper boy and his terrible and life risky job he has to do everyday.
Literally each poems of the second part are some kind of alter or opposite image of poem from part one. It has put me into some kind of oblivion at that point.
However, of you ask me what or how much evil inside me? The answer is simple. It is almost equal to the good you thought of me. Ha ha ha..
Devilish Smile....!
