Once there was a dragon, of great age and knowledge, who lived high on the peak of the Jade Mountain. This dragon was a scholar and thus more than content to spend his days studying ancient, secret knowledge as well as observing the world around him. He would spend long mornings talking to the new bamboo shoots as they pushed up through the soil, learning what it was that made them grow. The bamboo whispered to him about how they strove to feel the sun on their leaves, yearned for the wind that blew through the bamboo groves. In the afternoons, the dragon would talk to the fish and hear about their long journeys through the waterways from the mountains to the ocean. The fish spoke of the small streams that climbed hills and mountains, the wide rivers that cut through the valleys. They sang of the still water where the rice grew, the small pools of the forest, all moving towards the wide bottomless, roaring ocean. At night, the dragon would curl his massive body around the very peak of the mountain and call up to the stars, mapping their spinning journey and learning the stories of how they came to live in the sky.
Human kingdoms rose and prospered or were conquered and passed away into dust. The dragon began to feel a pain in his heart. The stories of the willow trees and the journeys of the birds did not enthrall him as they once had. So the dragon turned his attention inward, trying to find the source of his unhappiness. After much reflection, the dragon realized he was lonely. He had always lived alone on his mountain, observing but never truly touching the world around him, and his heart yearned for more. He wished for a companion, but of all the animals, plants, and creatures that lived with him on his mountain, there were none that did not die and wither in what seemed a blink of an eye.
Having no one to express his great loneliness to, the dragon began to write poems about how he longed for companionship, for someone to talk to and sit with. He wrote the love letters he would have written to his companion and hid them away inside the mountain.
One day, however, as the dragon was sitting at his writing desk on top of the mountain in his human form and writing yet more love poems, a great wind sprang up and blew the sheets of paper into the air.
Leaping up, the dragon tried to capture them, but his human body was too small, and he could not move fast enough or reach high enough. The poems blew away.
The wind carried the sheaves of paper high into the sky, twisting and turning among the stars as they looked on with interest. Finally, the wind blew the poems up into the celestial realm and straight to the Moon Palace.
The Jade Rabbit, Great Physician of the Moon Palace, stumbled across the sheaves of paper there. She had just finished a long day of grinding herbs for medicines and charting the bodies of all different celestial beings that came to her for aid. She was looking forward to a rest, so she did not look over the papers right away and merely took them with her to her rooms. Later, though, when she had made herself a cup of tea and unbraided her long white hair, she lit a lamp, sat at the window of her rooms in the great Moon Palace, and began to read the papers she had found.
When she discovered they were love poems, she made to put them aside, thinking they were too personal for her to read. The loneliness and the sadness behind the words struck her, however, and she continued to read against her better judgment.
She knew it was a great gift that had been given to her, to be allowed to live in the Moon Palace, granted immortality and the chance to serve all the celestial beings as Great Physician. Yet the Jade Rabbit was lonely as well.
After finishing the last poem, she went to her writing desk and wrote a poem of her own on the back of one of the papers she had found. She folded it and walked to the window; opening it, she cast the poem out into the wind.
The sheet slowly drifted down from the Moon Palace into the realm of earth and air, where it landed on Jade Mountain, home of a certain dragon.
The dragon had moped inside the mountain for many days after losing his poems. He had not eaten or slept and refused to come out, even when the birds sent a troop of monkeys to locate him. Finally, the sheer boredom from moping about his palace forced him to emerge onto the mountain surface. He trudged through the bamboo forest, barely stopping when the bamboo called out to him.
At the very top of the mountain, the dragon spotted something—a small square of folded paper. Picking it up, his heart leapt with joy as he realized it was one of his lost poems. When he unfolded it, though, he found something else written on the back.
"Loneliness sits heavily upon my heart.
I can barely find pleasure in a cup of tea,
The bend of the plum tree outside my window, once lovely, holds no joy now.
These things you also know."
For a long moment, the dragon stood there, reading and rereading the reply to his poems. Then he moved as fast as he could back down the mountain to his writing desk to write a reply.
"Monkeys come telling me of the birds' distress.
The bamboo calls out for my attention.
Only your words fill my head."
He did not know from where the reply had come, so he folded his own poem and cast it into the wind.
In the Moon Palace, the Jade Rabbit smiled when she came upon the poem caught in the branches of a cherry tree. She read it over, and then again, slower this time, before tucking it into her dress and heading for her writing desk.
"My life is medicines, work and duty
Here where I live alone in the walls of the moon
But your words make me smile again
I wonder if I might write something to make you smile too."
On the Jade Mountain, the dragon was awake, looking for a reply poem as soon as the sun had begun to touch the horizon. Finding the small square at last, half soaked from falling into a stream, he carefully laid the sheet out to dry while he went to find himself another ink stone, already composing his reply in his head.
Many poems were shared as the centuries passed.
Talk of loneliness turned to shared conversations about their studies. Talk of studies turned to deeper discussions and admission of love.
"We should meet," the Jade Rabbit finally wrote, "for I long to see you in person."
"If only I could travel to the Moon Palace," the dragon wrote her. "But I fear I am not powerful enough to cross over from this world into yours."
When she read that, the Jade Rabbit knew it was true and pondered how they could accomplish it anyway. Going to her workshop, she crafted with her power and knowledge a moon pearl. Combined with the dragon's strength, she thought, it could form a bridge between realm of the Moon Palace and earthly realm of the Jade Mountain so that she could pass down and see him face-to-face.
She hurriedly composed a letter with her plan and wrapped it around the moon pearl, casting it out the window.
As the letter and pearl drifted down to the mountain, a storm blew up. The wind and the rain battered against the pearl, crumpling the fine paper and tearing it away. The shreds of letter caught in the branches of a poplar tree. The pearl landed in a stream.
A fish was the first to chance upon the pearl and, not realizing what it was, swallowed the precious thing whole. It dissolved inside the fish, filling it with the power of the moon. The fish did not realize this, however, and continued on its way down the stream towards the ocean.
Far from the mountain where the stream turned into a wide, great river, a poor farmer caught the fish. He brought it back for his wife, who was with child. The farmer's wife roasted and ate the fish. A few months later, she gave birth to a boy child, who was born small and sickly but with great beauty and grace, for the knowledge and power of the moon dwelt within him.
Not receiving any word back, the Jade Rabbit became distressed and wrote the dragon asking why he did not use the pearl and form the bridge between the mountain and the moon. When the dragon heard of the pearl, he searched far and wide for it, but of course it was nowhere to be found. He wrote the Jade Rabbit with great sadness, telling her the pearl was lost, and she wept, for it would be centuries more until she would have the power to make another one. The dragon could not stand the idea that they might not meet. So he did what he had never done; he left the mountain, traveling among the humans, in search of the missing moon pearl.
But still the two remained parted.
