+أعطني الناي وغني فالغنا سر الوجود
+وأنين الناي يبقى بعد أن يفنى الوجود
+هل إتخذت الغاب مثلي منزلاً دون القصور
+فتتبعت السواقي وتسلقت الصخور
+هل تحممت بعطر وتنشفت بنور
+وشربت الفجر خمراً فى كؤوس من أثير
+هل جلست العصر مثلي بين جفنات العنب
+والعناقيد تدلت كثريات الذهب
+هل فرشت العشب ليلاً وتلحفت الفضاء
+زاهداً في ما سيأتي ناسياً ما قد مضى
+أعطني الناي وغني وانسى داء ودواء
+إنما الناس سطورٌ كتبت لكن بماء
