Surya Namaskar (Sun Salutation) Poem

I wish I could give credit to the author of this poem.  Years ago I copied it from a book.  Why do I think it came from an edition of Our Bodies Ourselves?  Hhhmm... if anyone has the book please check the glossary for "yoga" and let me know if it's in there!  The photo you see is of a poster I created.

With hands in prayer I face the sun
Feeling love and joy in my heart.

I reach out and let the sun fill me with warmth.

I bow before the sun's radiance
And place my face to the ground in humble respect.

I lift my face to the sun and then remember,

To achieve such heights,
I must be as the dust of the earth.

I stretch up towards its light,
Trying to reach the greatest heights.

And again surrender.

I stand tall as I remember,
the true sun is within me.
