Seimei Defeats Ashiya Dōman — The Great Onmyōji Duel

The story

In the twilight of the Heian period, when the refinement of courtly culture mingled with ancient beliefs, the air was rich with the echoes of secret incantations and whispered rivalries. At the center of this ethereal world stood two formidable figures: Abe no Seimei (安倍晴明), revered as the epitome of onmyōji wisdom, and Ashiya Dōman (蘆屋道満), a shadowy practitioner whose talents thrived in the murky corners of occult knowledge. The pulse of their legendary rivalry reverberated through the capital, where the silk-clad courtiers of Kyoto held their breath, ensnared by the allure of supernatural feats and arcane demonstrations. The contest that would enshrine their enmity in the annals of Japanese folklore unfolded one fateful evening, suffused with the scent of incense and the flickering glow of lanterns illuminating the noble gathering at the imperial court. It was Dōman, ever shrouded in an air of malign intrigue, who first proposed a challenge that would test the mettle of Seimei, the luminous onmyōji. Before a captivated audience, he summoned a lacquered box, flawlessly crafted and exquisitely adorned, and revealed the cunning ruse within: fifteen oranges, each carefully concealed from view. “Honorable Seimei,” Dōman said, his voice smooth yet laced with a venomous undertone, “if you possess the true mastery of divination, then reveal to me the fruits within this box.” A hush fell over the spectators as they awaited the response of the venerable sage. With an ashen demeanor and seemingly unfazed by the tensions of the moment, Seimei closed his eyes and gathered his thoughts in meditation. He drew upon a wellspring of knowledge, nurtured by years of study under the auspices of the celestial gods and sacred scrolls. “Fifteen oranges,” Seimei declared, opening his eyes and gazing steadily at Dōman as murmurs rippled through the assembly. The revelation struck like a lightning bolt; the count was indeed correct. A scowl creased Dōman’s brow, but masked beneath the veneer of grace he summoned a resolve to formulate a counter challenge. “I must not let this stand unreciprocated,” he said sharply, a tempest of cunning glinting in his eyes. “Now, I shall hide an object of my own. If you are as wise as they say, let us see if you can divine its essence.” Seimei accepted the challenge, and as Dōman secured a new box with equal precision, the court held its collective breath once more. Dōman, ambitious and proud, attempted to divine the hidden object. The atmosphere thickened with anticipation as he chanted incantations, his brow furrowed in concentration. In contrast, Seimei’s demeanor remained serene, imbued with an unshakeable confidence. In a deliberate and mesmerizing act of magic, Seimei transformed the very nature of the object contained within the box — sometimes depicted in legend as a rat metamorphosed into an exotic fruit, while other versions suggest the contents themselves were obscured by an enchantment that shifted their guise entirely. “I see nothing,” Dōman finally declared, his voice strained with disbelief as his visions clouded. The onlookers gasped as Seimei unfurled the secret: a simple box containing a fruit that echoed none of Dōman’s anticipations. Here, in that vivid moment, the true essence of their rivalry crystallized, with Seimei emerging not only victorious but as a figure of orthodox authority, holding steadfast against the spectral tides of Dōman’s heterodox dark arts. Yet the rivalry did not end with this contest of minds and magic. Dōman, ever resentful and embittered, resorted to yet more treacherous tactics by enlisting the aid of Seimei's own student, Shōren (昌連). Tempted by promises of knowledge and power beyond his years, Shōren faltered, revealing the secret scrolls that contained Seimei's methods and insights—a betrayal that seared the bonds of loyalty. Upon discovering this treason, Seimei remained unperturbed. Rather than unleash a savage retribution, he invoked the principles of Onmyōdō, embodying the balance between yin and yang that characterized his teachings. With his wisdom unassailed and his techniques secured, he approached Shōren and offered forgiveness, urging him to return to the path of enlightenment, underscoring the values of loyalty and duty over selfish ambition. Shōren, overwhelmed by guilt and the realization of his folly, returned to Seimei’s fold, abandoning Dōman’s sinister influence. These tales, woven into the fabric of classic Japanese literature, found fertile ground in the kabuki and bunraku performances of the Edo period, resonating through the ages as symbols of the struggle between the light of disciplined study and the lure of the clandestine arts. In kabuki plays like “Abe no Seimei” and in bunraku narratives, audiences witnessed the enchanting dramatization of wits clashing like the hills and valleys of the land, the noble onmyōji arrayed against the cunning machinations of Dōman, whose allure was forever tinged with darkness. And so, as the sun dipped below the horizon, casting an orange hue across the skies, the legacy of Abe no Seimei and Ashiya Dōman continued to thrive in the hearts and minds of those who sought wisdom in the balance of supernatural worlds. Their rivalry epitomized a quintessential struggle in Heian society: the tension between orthodox Onmyōdō, rooted in scholarly resolve and divine harmony, and the allure of the heterodox practices that electrified the imaginations of all who dared to explore the margins of the known universe. Their stories remain not merely reflections of their pretensions but mirrors for humanity, revealing deeper truths about ambition, loyalty, and the nature of power in an era that continues to capture our fascination.
