This edition of Poems of William Blake consists of three parts.
Songs of Innocence are cheesy, cliched, religion-inspired material.
Songs of Experience, including the infamous 'The Tyger', 'The Garden of Love', 'The Human Abstract', and others are reflective pieces inviting contemplation.
The Book of Thel was too symbolic for my current state of mind, so I turned to Wikipedia to grasp the gist of it.
So, 3 stars are medium rating for the whole, but I think I will revisit some individual poems from the Songs of Experience section in the future.
