What is the theme in The Nerve by Glyn Maxwell?

Passion is a major theme in the poem. When Maxwell urges his readers in his poem “The Nerve” to “cross a line” into the unknown, he might well be referring to coming alive with passion. Although there is also the sense of death in the poem, with such phrases as “a breeze of being gone,” there is a stronger pull that suggests one should use that realization of death to live life to its fullest, in other words, to live with passion.
