I am looking for the text of a poem that begins "Do not stand at my
grave and weep."  I have heard that it is a Native American poem.

Hello.

The poem is called "Goodbye." 

Although many web sites list the author as unknown, a few such as
Self-Help magazine attribute the poem to Gwydion Pendderwen.

Here is the text:

"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 sunlight 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 star that shines at night.
Do not stand at my grave and cry.
I am not there. I did not die."

Here is more information about Gwydion Pendderwen from a web page
devoted to him on a web site called "PSYCHE VAN HET FOLK":

Gwydion was also known as "Tom Delong."
See the results of this Google search:

I hope this helps.

There are also many sources that attribute the poem to one Mary E.
Frye, written in 1932.

Here are some links to make such an attribution:

I was actually able to find a site showing two different versions of
the poem and attributing two different authors.

have a look at this:
