In Poem 44 of Chapter 8 of Attar's Mokhtar Nameh, the poet explores the profound mystical concept that one's own ego or 'selfhood' (khudi) acts as the ultimate veil (pardeh) between the lover and the Divine. To attain true spiritual progress, the mystic must systematically 'cast out' their entire sense of independent existence, realizing that the self itself is the primary barrier to the beloved.
