In Chapter 10, Poem 23 of Attar's Mokhtar Nameh, the poet emphasizes that true eternal subsistence (baqa) is intrinsically linked to recognizing the 'path of signlessness' (the unmanifested, transcendent nature of the Divine). He suggests that without this spiritual realization, an individual remains 'behind the veil' of illusion. Merely possessing an everlasting existence without grasping this traceless reality means one has failed to experience the genuine essence of life and true eternal subsistence.
