In Poem 73 of Attar's Mokhtar Nameh, the poet uses the metaphor of the sea to contrast superficial worldly reputation with profound spiritual attainment. The poem asserts that in times of worldly disgrace, a true spiritual seeker does not chase after renown. Instead, like a diver seeking a precious pearl, one must plunge into the deep ocean of spiritual truth. The 'foam' cast upon the shore represents empty, superficial fame and distractions, while the 'pearl' found in the depths signifies true spiritual substance and divine reality.
