It Poetry is a deceptively simple art form. Poetry is the distillation of the poet's perception and response to the world.
Poetry can be highly personal and abstract, or it can be concrete and immediate.
It's almost as if it's written in some kind of code, and unless you were born with the ability to decipher this code, you may feel like you can't access its meaning. This is where the poem's structure comes into play. Each poem has its own internal logic and meaning. Most of the time you have to read a poem several times to absorb it. Poetry stems from an oral tradition.
