Analysis of the Rubai

This quatrain offers a philosophical reflection on the passage of time and the impermanence of human power and glory.

The wise sage and the child: The contrast between the wise old man and the young child symbolizes the cyclical nature of life and the passage of time.
The impermanence of power: The reference to Kay Kaus and Kay Khosrow, legendary Persian kings, highlights the idea that even the most powerful and influential figures are eventually consumed by time.
The passage of time: The phrase "so softly creeps" emphasizes the gradual but relentless nature of time's passage.

In essence, this rubai is a reminder that all human beings, regardless of their power or status, are ultimately subject to the passage of time.
