Campeyya Jātaka

The Buddha told this story, Jataka No. 506 of the Visatinipata's Matangavagga as recorded in the Pali Canon, while praising to his lay followers the observance of the Uposatha precepts. He explained that wise men of old had renounced even the glory of being a Naga king in order to keep such vows, and related a tale from a previous birth to show how far that renunciation had once been tested.

The Bodhisatta had once been a poor man who, witnessing the magnificent splendor of a passing Naga king's display, was seized with covetous longing for such glory. Through virtuous deeds and almsgiving performed afterward, he was reborn in the Naga world itself, in the resplendent underwater palace at the river Campa between the kingdoms of Anga and Magadha, where he became sovereign under the name Campeyya. At first he despaired at finding himself born into a serpent's form, but his attendants revered him, and in time he accepted his station and ruled the Nagas as their king.

Recognizing that only a human birth could carry him toward the full range of paramita perfections and complete awakening, Campeyya resolved to observe the Uposatha vows with unbroken purity. On the fourteenth and fifteenth days of the lunar cycle, he left his underwater palace, climbed into the human world, and lay coiled upon an anthill beside a public road. He invited any passerby to take his skin, flesh, bones, or blood freely, vowing he would neither strike with venom nor harbor anger no matter what befell him. His queen, Sumana, warned him of the dangers waiting in the human world. Between them they established three signs by which she would know if he had come to harm: the water turning turbid if he were struck, his form vanishing if a Garuda, a mythical bird of prey that hunts serpents, seized him, and the water running blood-red if a snake-charmer took him captive.

A young brahmin scholar, armed with potent charms and herbs, found Campeyya upon his anthill and overpowered him. He forced open his jaws, spat and squeezed acrid herbal pastes into his mouth, beat him, and destroyed his teeth in the struggle. Though Campeyya possessed a fiery breath capable of reducing his tormentor and the surrounding country to ash in an instant, he closed his eyes and endured every torment without the slightest flicker of malice, refusing to break the vow he had sworn. The brahmin forced the bleeding, starving serpent into a basket and carried him from village to village, making him dance and display his hoods before jeering crowds for profit.

After a month of captivity, Sumana saw the water run blood-red and understood at once that a snake-charmer had taken her husband. She searched until she traced him to Benares, where the brahmin was preparing to exhibit the dancing serpent before King Uggasena in the royal courtyard. Appearing in the palace, weeping, she revealed to the astonished court that the captive serpent was no ordinary snake but the mighty Naga sovereign of Campa.

Stricken with shame at what had been done under his own roof, King Uggasena ransomed Campeyya from the brahmin with gold, cattle, and villages, securing his immediate release. Campeyya then cast off his captive disguise and invited the king to visit his underwater realm, where Uggasena witnessed celestial wonders for seven days. When the king asked why anyone would abandon such splendor for the hardship of ascetic vows, Campeyya answered that genuine control and cleansing of the heart come only in the world of men. He longed for a human birth precisely so that he might pursue full awakening. Before the king departed, Campeyya pressed immense treasure upon him, enriching Benares and the surrounding land.

Concluding the teaching, the Buddha identified the characters across both lifetimes. Devadatta had been the brahmin snake-charmer, Sariputta had been King Uggasena, Rahulamata had been Queen Sumana, and the Buddha himself had been Campeyya, the Naga king who chose unbroken patience, khanti, and moral discipline, sila, over both vengeance and a glory he had once coveted and ultimately found far less than human birth.
