In Poem 25 of Chapter 4 in Attar's Mokhtar Nameh, the poet employs the metaphor of the 'traceless ocean' (بحر بینشانی) to illustrate the ultimate spiritual journey of annihilation and realization. When the seeker's heart merges into this boundless, incomprehensible divine ocean, it transcends the phenomenal world—described as the realm of the 'absent ones'—and attains the true 'essence of life' (روغن مغز زندگانی). This transformative transition signifies leaving behind spiritual separation and illusion to achieve an 'eternal Presence' (عین حضور جاودانی) and absolute unity with the Divine.
