一灯能除千年暗，一智能破万年愚
One Lamp Dispels a Thousand Years of Darkness, One Wisdom Breaks Ten Thousand Years of Ignorance
“A single lamp dispels the darkness of a thousand years; A single wisdom shatters the ignorance of ten thousand years.” — Avatamsaka Sutra (Huayan Sutra)
I. The Lamp: Symbol of Radiance
The fifteenth day of the first lunar month, known in antiquity as “Shangyuan,” marks the first full moon of the new year.
The ancients called night “xiao,” hence Yuanxiao—the Night of First Light. On this evening, countless lamps ignite in succession, from imperial palaces to bustling markets, from temple courtyards to humble homes, transforming thousands of households into realms of daylight. Yet these flames have never been mere instruments of illumination—
They are messengers of winter’s end and spring’s return. The fifteenth day arrives after立春 (Beginning of Spring), as rain waters approach and the earth’s yang energy stirs, though the night air remains chill. A single lamp becomes humanity’s invocation of spring, an unwavering warmth in the cold darkness.
They are prayers of the human heart turning toward light. Through long nights, lamplight offers intimacy. The ancients lit lamps to dispel physical darkness; Buddhists light them to illuminate the inner darkness of avidyā—fundamental ignorance.
This verse from the Avatamsaka Sutra reveals the deepest meaning of Yuanxiao’s lantern tradition: The darkness of a thousand years yields only to lamplight; the ignorance of ten thousand years yields only to wisdom.
II. From Imperial Ritual to Earthly Celebration
The lanterns of Yuanxiao trace their origins to the Buddhist practice of offering lamps to the Buddha.
During the reign of Emperor Ming of the Eastern Han Dynasty, as the Dharma first spread to the Central Plains, historical records indicate that the emperor, seeking to propagate Buddhist teachings, decreed that lamps be lit on the fifteenth night of the first month in both palace and monastery “to honor the Buddha through illumination.” Gradually, this custom flowed from royal temples into common households, merging with the Taoist “Three Primes” cosmology—specifically the blessing-bestowing Heavenly Official of Shangyuan—to become a national celebration.
The Tang Dynasty witnessed the apex of Yuanxiao illuminations. Within Chang’an’s walls, artisans constructed lantern wheels twenty zhang high, draped in brocades and adorned with gold and silver, igniting fifty thousand lamps clustered like flowering trees. The poet Su Weidao captured this spectacle:
“Fire trees and silver flowers merge; Starry bridges, iron locks open.”
This was physical splendor become spiritual solemnity. Each lamp represented a humble offering; each ignition, a summons to wisdom.
III. The Light of One: Dispelling Darkness and Continuing Transmission
“A single lamp dispels the darkness of a thousand years”—the profundity lies in the word “one.”
Lamps need not be numerous; one suffices. The darkness of a thousand years appears immeasurably dense, yet where lamplight reaches, illumination is immediate. Afflictions and habitual patterns accumulate like a millennia-old dark chamber, yet the wisdom of awakening, like a newly lit flame, instantly pervades all.
This recalls the Zen koans: When a disciple asks “What is Buddha?” the master answers “A dried shit-stick”; when asked “What is the Way?” the master replies “Ordinary mind is the Way.” Wisdom dwells not in distant realms but in the immediate turning of attention within this very thought.
On the night of Yuanxiao, as we ignite a single lamp, we also ignite our inner awareness:
- For children, the lamp is curiosity and hope;
- For wanderers, it is the path home and the ache of nostalgia;
- For the elderly, it is reflection and release;
- For practitioners, it is samādhi and perfect clarity.
Lamp passing to lamp, light reflecting light. The ancients crafted revolving lanterns, sky lanterns, lotus lanterns… intricate artistry, yet the essence remained always one fire, one point of radiance, one moment of sincere intention.
IV. The Awakening of One Wisdom: From Lantern Riddles to Zen Insights
Yuanxiao traditions include guessing lantern riddles—inscribing enigmas upon lamps, suspending them for others to solve, with prizes for correct answers.
This appears mere amusement, yet subtly embodies the “shattering of ignorance.” The riddle’s surface resembles avidyā, obscuring truth; the solution resembles wisdom, revealing original nature. The process of solving mirrors the transformation of consciousness into wisdom—from perplexity to sudden clarity, from meditation to penetrating insight.
Consider this classic riddle:
“In youth it wears black robes; in age, green garments.It lives its days in water; comes to shore for sleep.” (Name the creature)
The answer: the frog. Yet on a deeper level, is this not metaphor for human existence? We too change our “garments” through life’s stages, passing through the waters of worldly existence to find rest upon the shore of awakening.
One wisdom shatters ten thousand years of ignorance. This “wisdom” is not accumulation of knowledge but prajñā—insight transcending dualistic opposition. It enables us to perceive: affliction is bodhi, samsara is nirvana, the lantern light of Yuanxiao and the daily necessities of rice and salt are fundamentally one matter.
V. This Evening, of All Evenings: Reunion Amid Oceans of Light
Today’s Yuanxiao celebrations feature more brilliant illuminations than ever, yet not necessarily deeper sincerity. Neon has replaced candle flame; electronic lanterns have supplanted oiled-paper ones. Still, we need that “single lamp”—
We need it in moments that halt our hurried steps; We need it in corners that remind us what we treasure; We need it in the depths of mind where a long-forgotten flame awaits rekindling.
“Delighted to meet you. May we journey together, transforming this place into a warm and beautiful spring garden.”
Such is the modern Yuanxiao aspiration. The ancients offered lamps to Buddha as transcendence upward; we light lamps in gathering as flourishing toward warmth. Though paths differ, the destination converges: both employ radiance against emptiness, connection against isolation, wisdom against delusion.
Conclusion: Spring Lanterns Like Daylight, Wisdom Ever Luminous
The fifteenth day of the first month: the moon full among humankind.
As you pass through streets hung with lanterns, as you lift a warm sweet dumpling to your lips, as you glimpse that orange glow in some window—remember the Avatamsaka Sutra‘s teaching:
In a dark chamber of a thousand years, one lamp brings immediate light; in ten thousand years of ignorance, one wisdom brings immediate liberation.
This lamp may be the Yuanxiao flame, a teacher’s guidance, a good book’s inspiration, or the single thought of gentleness and clarity rising in your mind right now.
May this Yuanxiao night know endless lamps, wisdom passed from one to another. May we all become lamp-lighters, illuminating ignorance, ascending together to the spring mountains.
note：自从知晓这句话，每逢元宵节我都能想到这句话，今日请AI帮根据这句话写，居然这么好了，恐怖，以后人类的价值还能是什么呢？大概是感情，经历，组织，方向，以及偶尔的领悟和顿悟吧。
Ever since I came to know this verse, it comes to mind every Lantern Festival. Today, I asked AI to write based on it—how unexpectedly excellent the result is. Terrifying. What value will humans have left in the future? Perhaps emotion, experience, organization, direction, and occasional moments of insight and sudden awakening.
