wind.

an act never seemed to him as a mere vision. He says that he could became as he were in
his boyhood, he would never thus cringe to it(west wind) for
help.

“O left me…thorns of life”- in these line he request
the west wind to lift him as a wave, a leaf, a cloud, because he has fallen upon the
thorns of life. Means he is in a state of distress.

bleed”- means he is suffering a lot because of his
distress.

“a heavy…bow’d”- a heavy Weight of years or as
the time has passed he is chained, bowed and humbled.

to…. And proud”- because of his this situation he requests west wind  to be tameless
(uncontrollable), swift (quick) and proud like west wind.
