M6:736 — نفی ضد هست باشد بی‌شکی / تا ز ضد ضد را بدانی اندکی

This beyt functions as a philosophical pivot in Rumi's argument for mystical death. The preceding verses urge the seeker to "shatter" their ego-self (manī, or 'I-ness'), comparing this struggle to a lion attacking its own reflection in a well. Rumi now provides the logic behind this self-negation.

He invokes the classical principle that things are defined by their contraries: light is understood through darkness, health through sickness. Here, true "existence" (hast) is the Real, the divine ground of being. Its opposite (żidd) is the illusory, separate self—the ego. To negate this opposite, to "die before you die," is not to become nothing; rather, it is the very act of affirming and realizing true existence. The struggle against the ego is therefore not merely destructive but epistemological: it is how we come to know the Real Self that lies beyond it.

The verse serves as a bridge. It explains why the violent imagery of self-annihilation is necessary and leads directly into the following verses, which clarify that this "death" is not a physical end but a transformative one—a shedding of illusion to step into the light of reality.
