How can I study TS Eliot's The Waste Land?

The Waste Land is a very complex poem, with a lot of allegories and hidden meaning. It can be daunting, especially due to its length. However, it is worth spending time on it to properly understand it.

The poem is split into five sections: The Burial of The Dead, A Game Of Chess, The Fire Sermon, Death By Water, and What The Thunder Said. 

Not only is the poem ridden with allegory, it also has context in Eliot's own life.
