There was once a stone cutter who was dissatisfied with himself and with his position in life.
One day he passed a wealthy merchant's house. Through the open gateway, he saw many fine possessions and important visitors. "How powerful that merchant must be!" thought the stone cutter. He became very envious and wished that he could be like the merchant.
To his great surprise, he suddenly became the merchant, enjoying more luxuries and power than he had ever imagined, but envied and detested by those less wealthy than himself. Soon a high official passed by, carried in a sedan chair, accompanied by attendants and escorted by soldiers beating gongs. Everyone, no matter how wealthy, had to bow low before the procession. "How powerful that official is!" he thought. "I wish that I could be a high official!"
Then he became the high official, carried everywhere in his embroidered sedan chair, feared and hated by the people all around. It was a hot summer day, so the official felt very uncomfortable in the sticky sedan chair. He looked up at the sun. It shone proudly in the sky, unaffected by his presence. "How powerful the sun is!" he thought. "I wish that I could be the sun!"
Then he became the sun, shining fiercely down on everyone, scorching the fields, cursed by the farmers and laborers. But a huge black cloud moved between him and the earth, so that his light could no longer shine on everything below. "How powerful that storm cloud is!" he thought. "I wish that I could be a cloud!"
Then he became the cloud, flooding the fields and villages, shouted at by everyone. But soon he found that he was being pushed away by some great force, and realized that it was the wind. "How powerful the wind is!" he thought. "I wish that I could be the wind!"
Then he became the wind, blowing tiles off the roofs of houses, uprooting trees, feared and hated by all below him. But after a while, he ran up against something that would not move, no matter how forcefully he blew against it - a huge, towering rock. "How powerful that rock is!" he thought. "I wish that I could be a rock!"
Then he became the rock, more powerful than anything else on earth. But as he stood there, he heard the sound of a hammer pounding a chisel into the hard surface, and felt himself being changed. "What could be more powerful than I, the rock?" he thought.
He looked down and saw far below him the figure of a stone cutter.

There is an Indian story on the same vein
The Transformed Mouse Seeks a Bridegroom
On the shore of the Ganges there was a hermitage filled with holy men dedicated to prayer, self denial, repentance, the study of holy scriptures, fasting, and meditation. They drank only small amounts of very pure water, and mortified their bodies with a diet of bulbs, roots, fruits, and water plants. Their only clothing were loincloths made from tree bark.
The father of the hermitage was named Yajnavalkya. He had just finished bathing in the Ganges and was about to rinse out his mouth when a little mouse fell from a falcon's beak into his hand. After looking at it, he set it onto a fig leaf, bathed himself once more, rinsed out his mouth, and performed his penitential and other rituals. Then through the power of his holiness he transformed the mouse into a girl.
Taking her home with him to his hermitage, he said to his wife, who was childless, "My dear, take her in place of a daughter. Bring her up with care!"
Thereafter she was reared, loved, and nurtured. When she was twelve years old, and the wife saw that she was ready for marriage, she said to her husband, "Listen, husband, do you not see that it is past time for our daughter's marriage?"
He said, "What you say is quite right! So if she is willing, I will summon the exalted sun god and present her to him as a wife.
His wife said, "What could be said against that? Do it!"
Through the power of prayer and incantations the sun appeared without delay, saying, "Holy man, why do you summon me?"
The man answered, "Behold! Here stands my little daughter. If she will have you, take her as a wife!"
Having said this, he said to his daughter, "Daughter, does this exalted one please you, this sun god who illuminates the three worlds?"
The daughter said, "Father, he is too hot. I do not want him. Summon a better one!"
Hearing this, the wise man said to the sun, "Exalted one, is there a being more powerful than you?"
The sun answered, "Yes, there is a stronger one than I. The cloud, through whose cover I become invisible."
Then the wise man summoned the cloud and said to his daughter, "Daughter, shall I give you to this one as a wife?"
She answered, "He is black and cold. Therefore give me to another powerful being!"
Upon this the wise man asked the cloud, "Listen, cloud! Is there anyone more powerful than you?"
The cloud answered, "The wind is more powerful than I! Driven by the wind, I am scattered into a thousand pieces."
After hearing this, the wise man summoned the wind and said, "Daughter, does the wind please you most of all as a husband?"
She answered, "Father! He is entirely too inconstant. Summon a more powerful one instead!"
The wise man said, "Wind, is there anyone more powerful than you?"
The wind said, "The mountain is more powerful than I, for however strong I am, he still stands firmly against me."
Then the wise man summoned the mountain and said to the girl, "Daughter, shall I give you to this one in marriage?"
She answered, "Father, he is hard and rigid. Therefore give me to another one."
The wise man asked the mountain, "Listen, king of the mountains, is there anyone more powerful than you?"
The mountain answered, "The mice are more powerful than I, for they make holes in my body with violence."
With that the wise man summoned a mouse and showed him to her, saying, "Daughter, shall I give you to him as a wife? Does this mouse king please you?"
Seeing him, she thought, "He is of my own kind."
Her hair stood on end with pleasure, making her even more beautiful, and she said, "Father, make me into a mouse and give me to him as a wife so I can fulfill the domestic duties prescribed for my kind!"
Through the power of his holiness he transformed her into a little mouse and gave her to the other mouse as a wife.
