Songs of Innocence and of Experience by William Blake, the Lamb and the tyger.

Hie thee home wailing wights,

Here comes William Blakes

Put y’all in woe,

The shepherd’s sweet loot

Thy tongues shall fill with praise

Beware not to fall in his fiery blaze

Nineteen poems about innocence, full of glee and joy, talks about the birds and their songs, and how spring surely comes, heavenly delights awaits for he who remains in God’s pious lights, which burn bright even in darkest night.

So, done with the rhymes it is not easy, even the tiger breaks its own poem symmetry with that of its own fearful one. Twenty-six poems about experience with this of the tiger being the most iconic of all of Blake´s poems, in it he asks this question about God in regards of the tiger:

Did he smile his work to see?
Did he who made the Lamb make thee?
