M1:1139 — پس به ضدِّ نور دانستی تو نور / ضدِّ ضد را می‌نماید در صدور

Translation: So you knew light by its opposite, / For every opposite reveals its counter-opposite in its appearing. Meaning: We truly grasp the nature of things not just by their presence, but by understanding their antithesis; darkness, for instance, illuminates the very concept of light.

This verse, situated within the explanation of love, offers a pivotal insight into Rumi's epistemology: knowledge through opposition. I have stated repeatedly, and reiterate here, that Rumi emphasizes that the sun is its own proof (āftāb āmad dalīl-i āftāb). Truth, in other words, is self-evident and requires no external arguments or the candle of reason and philosophy for its substantiation. Yet, in this very couplet, Rumi teaches us that while light is inherently clear and its own witness, human experience often leads us to a deeper understanding of light through its opposite, darkness. This is a profound insight: though we find light in its essence, our comprehension of it is deepened by comparing it to its absence, to darkness.

I have previously noted that some have called Rumi the 'Hegel of the East,' but I assert unequivocally that if such a comparison is to be made, one should rather say Hegel is the 'Rumi of the West.' Why? Because Rumi, centuries before Hegel, paid profound attention to this dialectical and opposition-centric principle. He understood acutely that phenomena do not acquire meaning in a vacuum; if it were always day, we would not grasp the full value of light as we should, and if darkness did not exist, light would not reveal its complete meaning to us. This is akin to the air that constantly surrounds us, whose pressure we only truly perceive in its absence or by comparing it to higher or lower pressures. Existence reveals itself to us through its internal contradictions and struggles.

So when Rumi states, "So you knew light by its opposite," he means that our perception and understanding of light are contingent upon the experience of darkness, upon the absence of light. This is a form of 'inference' or 'signification' (dalālat). However, one must be careful not to mistake this inference for the 'truth' itself. A shadow also points to the sun, but it is not the sun itself. Rumi says: "Though the shadow gives a sign of it / The sun ever bestows the light of life." The shadow's inference is a 'dead inference' (dalālat-i murda); it is a distant sign. But light itself is a 'living proof' (dalīl-i jāndār); it is a direct and unmediated presence. Thus, knowing through opposites is a stepping stone to reaching the truth itself, not the entirety of it.

This understanding of opposition is itself a part of 'knowledge' (maʿrifat). I have also noted elsewhere that al-maḥabbat thamarat al-maʿrifah — 'love is the fruit and outcome of knowledge and recognition.' One cannot love something one does not know. Just as in the story of Luqman and the bitter melon, the master, in his ignorance of the melon's bitterness, could not tolerate it, while Luqman, through his profound knowledge and love for his master, found the bitterness sweet. This illustrates that knowledge, even the comprehension of contradictions and bitterness, is a prerequisite for attaining higher levels of love and acceptance. Understanding how the world operates through its opposites is itself a foundational knowledge that prepares a human being for deeper insights.

Key takeaways

• Understanding phenomena through their opposites (e.g., perceiving light through darkness) is a fundamental epistemological principle in Rumi's thought.
• Rumi recognized the importance of opposition in grasping existence and phenomena centuries before Western philosophers; this is an original insight.
• Knowledge through contrast is a form of 'inference' (dalālat) that guides us toward truth, but it is not the truth itself; truth is self-evident.
• Comprehending how the world functions through its opposites is a crucial step in the journey of 'knowledge' (maʿrifat).
• "Love is the fruit of knowledge" (al-maḥabbat thamarat al-maʿrifah); thus, an accurate perception of reality, including its contradictions, is a prerequisite for true love.
