Poetry, can anyone translate this poem? pls...

It doesn't make a lot of sense to me either but I'll give it a go. What if the transport being talked about is the passage of time and the author is talking about learning about this passage of time by the experience of living? Time seems to pass more slowly when we are upset. Althernatively this poem either seems full of self pity or is contrasting different types of pain which we can learn to transport with us throughout our lives. Blind men learn the sun not by sight like most of us but by feeling it which is why I think maybe the first idea is better. To die of thirst believing that there is water nearby would not only be ironic if there actually were but speaks of false hope, another kind of pain, if there isn't. The next verse seems comparatively clear it talks about a person who is homesick, but nevertheless has to stay in that foreign land tormented with thoughts of home. Maybe it means that there are a lot of people who write about such things (that's the ascending in ceaseless carol). I think the reference of the mysterious bard would be to shakespeare, maybe it means that although there is a lot of these experiences around, they are either so common that we no longer take any notice of them or since we are not all of the calibre of shakespeare then we cannot hear and comprehend the sorrow and pain of the world nor do we express it well. It's not a poem I have ever looked at before and I am only guessing but would like to know what you think.
