what do you like most about the poem"The Laburnum Top"

The spiritual message  given in the poem is most appealing.The man is compared with Gold Finch and the earth with the tree.Man enters deep in the worldy pleasure like Gold Finch  and keeps moving in worldy activities but finally he launches a way towards the heaven as Gold Finch flies away towards the infinite sky.The Laburnum tree,the earth  is left again alone and empty.The poet uses imagry to make the poem beautiful.
