Do not stand at my grave and weep,
    I am not there; I do not sleep.
    I am a thousand winds that blow,
    I am the diamond glints on snow,
    I am the sun on ripened grain,
    I am the gentle autumn rain.
    When you awaken in the morning's hush
    I am the swift uplifting rush
    Of quiet birds in circling flight.
    I am the soft starlight at night.
    Do not stand at my grave and cry,
    I am not there; I did not die.

Mary Frye, who was living in Baltimore at the time, wrote the poem in 1932.
