Touching poem

Lol... I am not a poem lover, but this one is really touching and lovely

Do not stand at my grave and weep
I am not there, I did not sleep

I am the thousand wind that blows
I am the diamond glints of snow
I am the sunlight on ripened grain
I am the gentle autumn's rain

Do not stand at my grave and cry
I am not there, I did not die

(again...taken from tv series, dunno who's the author)
