In Jalaluddin Rumi's Masnavi, as the hare and the lion near the well, the hare deliberately falls behind and acts terrified. When the lion questions this sudden hesitation, the hare points to his pale, trembling state, claiming his yellow complexion is undeniable proof of his terror regarding the rival lion. Rumi elevates this narrative moment to explore the philosophical relationship between the visible and the invisible, asserting that outward physical signs inevitably reveal the inner condition of the heart. Just as a yellow face indicates suffering or fear, and a red face denotes joy and gratitude, outward indicators such as color, scent, and tone of voice act as "informers." Rumi emphasizes that the spiritually realized individual (the gnostic) does not ignore the physical world, but rather reads these superficial manifestations to accurately discern a person's hidden, internal reality.
