How can these symbols or images relate to the definition of the poem?

The narrator expresses his despair with diametrically opposed concepts. He is unable to rest, and yet he has no fight left in him. He is optimistic yet afraid, he is ablaze yet frozen. He is soaring, yet cannot take off; he has nothing, yet he holds the whole world. Though there are no locks strong enough to imprison him, he cannot escape. The narrator feels he has no control over whether he lives or dies. He can see without his eyes, and complains without a tongue. He says he wishes to expire, and yet demands strength. By line 11 he reveals a less paradoxical contrast: that he loves another therefore must not love himself. He revels in the joy of the sadness and discomfort of this love, and although the situation is almost like a living death, the cause of his pain is his greatest pleasure.
