The cup of Jamshid is still glowing, but the art of empty play is no longer royal.

This profound couplet speaks to the ephemeral nature of glory and the illusion of power. The 'Jamshid' refers to a mythical king, symbolizing great, enduring glory. The poet suggests that even the brilliance of such mighty empires, represented by the lit glass, cannot sustain the superficiality or pretense of a mere 'mirror game.' True greatness, he implies, is not found in superficial displays of wealth or status, but in genuine depth.
