Thusa Jataka

At the Bamboo Grove, the Buddha addressed King Bimbisara concerning his own son, Ajatasattu, whose mother had carried a strange craving to drink blood from the king's own knee while pregnant with him. Despite the ominous sign, Bimbisara raised the boy with full royal honor. At sixteen, admiring his father's majesty and power, Ajatasattu grew consumed with the desire to kill him and seize the throne, confiding the plan to his own attendants. The Buddha told the troubled king a story from an age long past to show him how such a danger had once already been met.

In that former age, the Bodhisatta was a renowned teacher at Takkasila. When a young prince of Benares completed his studies there, the teacher foresaw, decades before the danger would ever arise, that this prince's own future son would one day threaten his life. He composed four protective verses and taught the prince to recite them at precisely the right moments once he came to the throne.

Grown older, the prince became king, and in time his own son began plotting exactly as foreseen. The son first poisoned his father's rice, but the king recited the first verse, comparing a rat's sharp instinct for telling grain from husk, and the prince, certain his plot had been read outright, abandoned it and fled.

Urged on by conspirators to strike during a formal court assembly, the prince next planned a sword attack, only for the king to recite the second verse, naming secret counsel taken in the wood and plots whispered ear to ear. Convinced once again that his father already knew everything, the prince fled a second time.

Reassured by his own attendants that the king still suspected nothing, the prince positioned himself to ambush his father on the palace stairs. The king's third verse spoke of a monkey who had once cruelly crippled its own tender offspring, and the prince, shaken by the comparison, retreated once more without striking.

Finally the prince hid beneath the royal couch itself, waiting in the dark. As the king entered, he recited the fourth and final verse, likening the hidden plotter's cautious, creeping movements to a one-eyed goat straying through a mustard field, and the terrified prince understood at once that he had been found.

Exposed a fourth time with nowhere left to hide, the prince surrendered himself and begged for pardon. The king chose not to kill him but had him imprisoned under guard, living out the remainder of his own reign in peace while reflecting often on the wisdom of the teacher who had armed him so long ago. Only when the king died a natural death was the prince finally released, taking the throne at last without having had to seize it by force. The Buddha closed the teaching by revealing that he himself had been that teacher of Takkasila, whose foresight had protected a kingdom two generations removed from the very danger he had first perceived. Jataka No. 338 of the Pali Canon records the tale under this telling, offered directly to Bimbisara as he faced the same danger from his own son Ajatasattu.

What makes the teacher's gift so unusual is that he gave it to a student who was not yet a father, for a danger that would not exist for another generation. The verses sat unused for decades, waiting for a threat that had not yet taken shape, which meant the king carried real protection into his reign without ever fully knowing when, or whether, he would need it.

Each attempt failed for a different reason on its surface: a verse about rats, about whispered counsel, about a cruel monkey, about a straying goat. Yet every one of them worked by convincing the prince that his father already knew more than he actually could have known through ordinary means. The king's real power lay not in secret knowledge of each specific plot but in a prepared response calm enough to look, every single time, exactly like it.
