In Attar's Mosibat Nameh, the story of Majnun preferring the word 'La' (No) over all others because it was uttered by Layla serves as an allegory for the mystical path. In Sufi philosophy, 'La' (the first word of the testimony of faith, 'La ilaha...') represents the absolute negation of the self, ego, and the phenomenal world. Majnun's adoration of his beloved's rejection illustrates how the mystic welcomes trials and negation as a means to achieve annihilation in the Divine.
