I think "same" refers to all the stuff in the sentence(s) before. You didn't excerpt it all, so I can't help any further.
"We after a manner see" I believe just means "Unlike sorrow, which is blind, we are able to see, after a period of time".
But poetry or poetic writing is not my strength, so take this with a grain of salt. This sort of writing is more about style than content, it seems to me.
Hope that helps.
