The poem
If hands could free you, heart, Where would you fly? Far, beyond every part Of earth this running sky Makes desolate? Would you cross City and hill and sea, If hands could set you free?
I would not lift the latch; For I could run Through fields, pit-valleys, catch All beauty under the sun-- Still end in loss: I should find no bent arm, no bed To rest my head.

This poem is so true and so perfect and i wanted to complement you on a job well done someone should!!
philip Larkin is at the crossroads.He is being so emotional that he wants to give freedom to his heart. At the sametime, he believes that life without one's heart is useless and not worth it.That's why he prefers to live with his heart.
