M1:278 — هر دو صورت گر به هم ماند رواست / آب تلخ و آب شیرین را صفاست

Translation: It is valid for two forms to resemble each other; For both bitter water and sweet water possess clarity.

Meaning: Two phenomena or entities may appear identical on the surface, yet their inner essence and nature can be profoundly different, just as both sweet and bitter waters can be equally clear and limpid in appearance.

This couplet from the Masnavi is not merely a poetic observation; it is a profound epistemological key to understanding the world. I believe that Mawlana issues a fundamental warning here: beware of the pitfalls of superficiality. "It is valid for two forms to resemble each other" means the world is replete with misleading similarities. Both bitter water and sweet water are clear; both might tempt a thirsty person. Yet, one is life-giving, the other destructive.

Mawlana introduces this point immediately after the story of the Parrot and the Grocer, a tale that vehemently emphasizes "bāṭin-bīnī" — perceiving the inner reality of events. The lesson of that story was that we should not judge actions by their appearances; what might seem like a murder could, in fact, carry a deeper meaning. This couplet continues that very lesson: there are people who are outwardly like "water," meaning they appear human, but inwardly, one is sweet water and the other bitter. It is here that Mawlana promptly concludes: "Since many devils have human faces, one should not give one's hand to every hand." Devils, too, come in human guise, with alluring exteriors.

This wisdom applies not only to individuals but pervades all phenomena. Mawlana uses this very couplet as a subtle yet profound segue into distinguishing between magic (siḥr) and miracles (muʿjiza). Outwardly, both are extraordinary phenomena; both can inspire awe or fear. Prophets were even accused of sorcery because superficial observers were unable to differentiate the sacred root of a miracle from the deceptive root of magic. But intrinsically, one comes from Truth and for guidance, the other from trickery and for delusion. Even the impact of a miracle, in Mawlana's view, has a limited ceiling; what endures and settles in hearts is potent, divine speech, not temporary displays.

More profoundly, Mawlana extends this criterion even to comparing the utterances and actions of the mystic and the misguided. Did not Pharaoh also declare "Ana al-Ḥaqq" (I am the Truth/God)? And did not Mansur Hallaj utter the same words? In terms of form and lexicon, both were identical: "It is valid for two forms to resemble each other." But "that 'Ana' of Mansur brought mercy; that 'Ana' of Pharaoh brought damnation." One came from Pharaoh's arrogance and opposition to God, the other from dissolution and absorption into the Divine Essence. One brought damnation, the other mercy. Again, the exterior was the same, but the interior was, without a doubt, fundamentally different.

Similarly, regarding faith and hypocrisy: both the hypocrite (munāfiq) and the believer (muʾmin) pray in the same mosque, performing prostrations and genuflections. The form of the action is identical, but the intention and motivation are entirely different. The believer prays out of divine command and obedience, while the hypocrite acts out of malice and pretense. One achieves ultimate victory, the other spiritual defeat. This is why I say, "In the human realm, judging and understanding are exceedingly difficult." Just as "a tree trembles from the axe's blow" and "another tree from the morning breeze;" both move, but one towards death and the other towards life. It is our duty, in "tafaḥḥum" (empathic understanding) of human affairs, not to be misled by these deceptive appearances but to delve into the core and depth of the matter.

Key takeaways

• Outward appearances can be deceptive; discerning the truth requires penetrating to the inner essence of things.
• Devils can appear in human guise in the world, necessitating caution in choosing companions and judging individuals.
• Even seemingly identical actions or statements can have opposing roots; intention and inner core give meaning to an act.
• Miracles and magic, or faith and hypocrisy, may resemble each other in form, but they differ profoundly in essence.
• For a correct understanding of the world and people, one must shun "superficiality" and embrace "inner vision"; this is key to human "empathic understanding."
