In poem 100 of Attar's Mokhtar Nameh, the carnal soul (nafs) is strongly condemned and metaphorically depicted as a faithless 'dog' (سگ نفس). The speaker implores the Divine to inflict suffering upon this baser aspect of the self because of its inherent disloyalty and hindrance to spiritual devotion. This metaphor emphasizes the unruly, animalistic nature of the ego that must be disciplined and subdued on the Sufi path.
