Robert Frost's "The Demiurge's Laugh"

The Demiurge's Laugh

    IT was far in the sameness of the wood;
    I was running with joy on the Demon's trail,
    Though I knew what I hunted was no true god.
    It was just as the light was beginning to fail
    That I suddenly heard—all I needed to hear:
    It has lasted me many and many a year.
    The sound was behind me instead of before,
    A sleepy sound, but mocking half,
    As of one who utterly couldn't care.
    The Demon arose from his wallow to laugh,
    Brushing the dirt from his eye as he went;
    And well I knew what the Demon meant.
    I shall not forget how his laugh rang out.
    I felt as a fool to have been so caught,
    And checked my steps to make pretence
    It was something among the leaves I sought
    (Though doubtful whether he stayed to see).
    Thereafter I sat me against a tree.

I chose this poem by Robert Frost because I feel that I can directly relate to it. We all have demons in our lives that we must deal with, and I feel like I'm constantly losing sight of what is important in life and constantly being tricked by my demon to believe and pursue what is not.
A literary device that Frost uses in this poem is a persona. The persona in this poem is a person who has basically taken a turn for the worst, but then realizes it and stops themselves in their own tracks.
