The underlying theme of Western poetry is mortality. The theme of carpe diem asks us to seize the day because we have only a limited number of them. … - Billy Collins

I was raised in a fairly strict religious family and attended 16 years of Catholic schools. I feel now that my sense of the spiritual is directly connected to my sense of wonder, my ability to be amazed by the fact of my existence in all its vital impermanence AND by the spectacular environment I wake up to every morning. I am guessing that this sense of wonder is what the creator, if there is one, is still feeling.

The person in the poem is a character like a character in fiction whom the poet has invented--without clothes or a family, or a place of birth, just a voice--to convey himself. Any resemblance he bears to the poet you meet on a signing line is slightly less than coincidental. Meeting the author is one of life's most reliably disappointing experiences, not because authors are such nasty people, but because you have already met them under the best possible circumstance--on the page.

It is important for the poet not to be emotional because you cannot see the world clearly with tears in your eyes.
