The poetry of Hafez is quoted by Iranians the way others quote Shakespeare--constantly. They often open a book of his poetry to a random page to find a quote applicable to their current wish or problem. This bi-lingual book is set up to be used that way. You make a wish, open to a random page, and read the original Persian and/or English translation, and get a kind of response to your wish. What the translator, Abbas Kashani, has added is an "Interpretation" of the lines to help you apply them to your own wish or problem. Several passages of Hafez from this book and others were used by Rea Keech in his novel A Hundred Veils.
