In Section 48 of Sana'i's Hadiqat al-Haqiqah, the poet employs the allegory of a man on a moving ship who mistakenly perceives the stationary shore as moving. This optical illusion serves as a metaphor for the worldly, materialistic person (mard-e donya-parast) who is deceived by the transience of the world. Just as the passenger is unaware of his own movement and projects it onto the shore, the worldly individual is blind to his own transient spiritual state, mistakenly believing his material existence to be permanent and stable.
