As the cool winter breeze begins to sweep through the mountains and fields of the Lanna kingdom, and the calendar marks the full moon of the twelfth lunar month, a giant golden moon rises to the center of the sky, casting a gentle glow over this ancient civilization. In a night that should be naturally silent, it is instead filled with the spirit of unity and the power of faith. The deep indigo night sky is gradually painted with thousands of tiny golden lights rising from the earth, piercing through the trees and temple rooftops. This creates a “sea of lights” drifting gracefully, like giant fireflies journeying toward the gates of heaven.
The magnificent sight of “Sky Lanterns”—or what the Lanna locals simply yet powerfully call “Fai” is not merely a visual spectacle or a light show for tourists. In every moment that the flame glows within the clean white paper lantern, it carries the “breath of culture” and the roots of beliefs deeply embedded in the blood of Northern Thais for centuries. The flame serves as the engine for prayer, while the rising hot air acts as the vessel carrying the pure aspirations of humanity through the floating of lanterns to the ears of the deities.

 Worshipping Phra That Kaew Chulamanee in Heaven
The true origin of the floating of lanterns in Lanna culture is intimately tied to Buddhist beliefs. The Lanna people are determined to worship “Phra That Kaew Chulamanee,” a celestial pagoda believed to enshrine the hair and the holy tooth relic of the Lord Buddha. However, this important relic is not located on Earth; it is situated in the Tavatimsa Heaven, a realm far beyond human sight or reach. Therefore, the floating of lanterns was created to serve as a Buddhist offering—a beacon of light to carry prayers, intense faith, and pure intentions through the atmosphere to pay homage to the relic in heaven.

Yi Peng The Convergence of Heaven and Earth
The tradition of the floating of lanterns takes place during the “Yi Peng Festival,” or the full moon of the second month according to the Lanna calendar. During this time, the northern weather becomes pleasantly cool, and the sky is clear and cloudless, making it perfect for floating lanterns to rise steadily into the heights. Locals gather at temples or activity grounds, preparing lanterns made of light kite paper and bamboo frames. Lighting the fuel at the base to create heat and lift is like awakening the power of faith, before slowly letting the floating of lanterns proceed according to the wind and the strength of their desires.

The Meaning of “Releasing” Letting Go of Suffering
Beyond worshipping the relic, the floating of lanterns carries the symbolic meaning of “dispelling bad luck” (Sadaw Kraw). Lanna people believe that the floating of lanterns is the act of casting away sorrow, suffering, illness, and misfortune from themselves and their families. Before floating a lantern, many write their names or prayers on the paper, making a wish for their lives to be as bright and soaring as the light in the sky. In some areas, small coins are placed inside the lanterns as an act of charity, believing that whoever finds the fallen lantern will receive a gift, passing on good fortune through our floating of lanterns.

The Lantern of Wisdom and Eternal Faith

When the final light of the last floating lantern fades into the clouds, what remains in the darkness is not just ash or bamboo frames, but the fulfillment in the hearts of Buddhists who have served as a bridge of merit to heaven. Lanna sky lanterns are not just a recreational activity; they are spiritual architecture crafted from intense faith, representing a hope that never disappears from the Lanna way of life.

At the moment two hands gently release the lantern, it symbolizes “letting go” and “offering.” We let go of the year’s suffering through the floating of lanterns and offer a virtuous heart to worship Phra That Kaew Chulamanee. The small lantern, shrinking until it becomes a star in the sky, acts as a bridge connecting the human world to the realm of deities.

Furthermore, the floating of lanterns serves as a powerful reminder for living. The soft light within the lantern teaches us that as long as we have the light of wisdom and confidence, life will always have the lift to rise above the darkness of suffering. This cultural heritage is not just a beauty that attracts the world’s eyes, but a “lamp for the soul” passed down through generations—a testament that as long as the night of the twelfth full moon is painted by the floating of lanterns, the hope and brightness in the human heart will never fade away with time.
