In Chapter 21, Poem 19 of Attar's Mokhtar Nameh, the poet employs the agricultural metaphor of sowing and reaping to illustrate the inescapable consequences of human actions. The poem emphasizes that the true nature of one's deeds—whether they lead to heaven or hell—may remain hidden in the present. However, just as seeds inevitably bear fruit, current actions determine one's future spiritual state. The reference to the 'pen' that has already written underscores the fixed nature of past actions, urging an active awareness of how today's deeds shape tomorrow's ultimate reality.
