I read the Forward this morning and I'm about to sit down and tackle poem/commentary but don't exactly know how I'm going to go about it...

Do I read the whole poem through then head to the commentary while revisiting the poem

or

Read the commentary straight after the section of the poen it applies to e.g. read lines 1-4 then the commentary

or

Read the commentary all the way through before the poem itself.

I'm being ridiculously indecisive about this!
