In Chapter 47, Poem 68 of Attar's Mokhtar Nameh, the mystical journey of love is depicted as an arduous, round-the-clock ordeal. The seeker is compared to a candle that must endure two distinct forms of suffering:

1. The Burning of the Night (سوز شب): Symbolizes the active, agonizing yearning and burning of the soul during the hours of private devotion.
2. The Death of the Day (مرگ روز): Symbolizes the quiet extinction, self-effacement, or annihilation of the ego during the day.

This continuous cycle of active burning and passive extinction represents the ultimate difficulty of the spiritual path, where the mystic must entirely lose their selfhood.
