In Chapter 12, Poem 33 of Attar's Mokhtar Nameh, the poet explores the theme of spiritual self-deception and the illusion of spiritual wealth. The 'poor heart' mistakenly believes itself to be free and 'full' (spiritually rich), only to realize its profound emptiness. Attar uses the metaphor of mistaking ordinary 'beads' (مهره) for precious 'pearls' (در) to illustrate how the spiritual seeker often overvalues their own flawed actions and limited understanding, confusing superficial piety or false achievements with genuine spiritual worth.
