In Poem 38 (Chapter 6) of Mokhtar Nameh, Attar explores the mystical transition from intellectual questioning ('why and how') and spiritual bewilderment ('madness') to a profound inner realization. The central metaphor involves the speaker knocking on a door for a lifetime, only to discover that the knocking originated from within himself. This paradox illustrates a core Sufi concept: the ultimate truth and the Divine presence are not external entities to be sought outside, but an inherent reality already residing within the seeker's own soul, highlighting the ultimate unity of the seeker and the sought.
