What does wine refer to in the poem Rubaiyat?

Wine is used symbolically throughout the "Rubaiyat" of Omar Khayyam to represent life, joy, pleasure, indulgence, and escape from the harsh realities of existence. It also symbolizes the fleeting nature of time and the transience of human life, reminding readers to savor the present moment. In some instances, wine serves as a metaphor for spiritual intoxication and connection with the divine.
