In Book 2 of Jalaluddin Rumi's Masnavi, as Dhu al-Nun's friends visit him in prison, the narrative introduces a profound spiritual metaphor based on the Quranic story of Moses' cow. In this traditional narrative, a murdered man is momentarily resurrected to name his killers after being struck with a piece of a sacrificed cow. Rumi reinterprets this miracle as an allegory for spiritual awakening, equating the sacrificed "cow" with the nafs (the carnal soul, or fleshly ego). Rumi asserts that "killing the cow" is an essential condition of the Sufi path. By mortifying base earthly desires and sacrificing the ego, the hidden, divine spirit is brought back to life. Just as the resurrected man in the story exposed his murderers, the spiritually awakened soul is freed from the "heavy body" and gains the clairvoyance to recognize divine secrets, perceive ultimate realities, and expose the deceptive traps of the ego and the physical world.
