In Chapter 46, Poem 4 of Attar's Mokhtar Nameh, the morning (dawn) is personified and compared to a diver in the "ocean of the sky." The poem advises the morning to maintain steadfastness and hold its breath, playing on the concept of Subh-e Sadeq (the true dawn). The shining of the sun is depicted as a manifestation of the morning's "sincerity" (صدق), requiring the disciplined restraint of a diver seeking pearls.
