But the earth ' s rotation doesn ' t affect ground speed . <| sep |> I think the weakest stanza is the third the middle of the poem , starting with We can ' t forget the fact . I think this is the weakest because from the context of your poem I ' m lead to disagree with the line a fact today often obscures . Today , the day that is difficult , does not seem to be the day that obscures the fact that This too shall pass . Is it not every other day that obscures that fact ? You never KNOW that fact on any other day , but it is only the days like this one that the fact suddenly becomes REAL . Suddenly , whether you like it or not you don ' t , you DO know it . This is the author understanding the teaching that This too shall pass , through actual experience . The best stanza , then , is the last . This is where the true emotion emerges . It ' s palpable I , the reader , can feel and touch it . But , the mistake is in thinking that the fight is against the advice . It ' s against the reality , which the author still conceives to be the advice . This stanza is where the advice transforms into the KNOWING through the lashing out and resistance . Which brings me to a previous line easy to hear and hard to know . I think the author is saying hard to know because he doubts that he knows . But , I think the author ' s subconscious meaning the one that may not reach the surface is that the experience of knowing is hard . The knowing is a present reality , but coming to terms with the knowing is hard because of the emotional resistance hence the reason for the final stand the last stanza . I love the conclusion in the last two lines . If this piece could be improved , I think it would be through reevaluating the third stanza , and more broadly by asking is the difficulty in KNOWING a difficulty in not knowing , or is it a difficulty of not wanting to know ? Moving piece , and I wish you all the best .
