In Chapter 6, Poem 21 of Attar's Mokhtar Nameh, the poet explores the theme of spiritual transcendence beyond both the material and spiritual universes (the 'two worlds'). By engaging in deep introspection and metaphorically splitting open the heart with profound thought, the seeker reaches the 'seventh veil' of the heart, identified as the soul (جان, jān). Through this ultimate inner journey, the seeker discovers a transcendent realm that exists entirely beyond the confines of the conventional two worlds, emphasizing that true spiritual discovery occurs within the deepest layers of one's own being.
