In this brief poem from Attar's Elahi Nameh, the Sasanian king Kisra delivers a concise spiritual lesson to his court musician, Barbad. Kisra asserts that a life free from sorrow requires a fundamental internal shift rather than external acquisitions. He identifies envy as a primary obstacle to happiness, advising Barbad to expel it from his heart. Furthermore, Kisra teaches that true freedom and joy are found in contentment with the Truth (Haqq). This exchange encapsulates core Sufi values, illustrating that genuine liberation stems from spiritual satisfaction and the conscious elimination of negative internal traits.
