RĀJOVĀDA JĀTAKA.

(Fausböll, No. 151.)

Once upon a time, when Brahma-datta was reigning in Benāres, the future Buddha returned to life in the womb of his chief queen; and after the conception ceremony had been performed, he was safely born. And when the day came for choosing a name, they called him Prince Brahma-datta. He grew up in due course; and when he was sixteen years old, went to Takkasilā,[26] and became accomplished in all arts. And after his father died he ascended the throne, and ruled the kingdom with righteousness and equity. He gave judgments without partiality, hatred, ignorance, or fear.[27] Since he thus reigned with justice, with justice also his ministers administered the law. Lawsuits being thus decided with justice, there were none who brought false cases. And as these ceased, the noise and tumult of litigation ceased in the king’s court. Though the judges sat all day in the court, they had to leave without any one coming for justice. It came to this, that the Hall of Justice would have to be closed!

Then the future Buddha thought, “From my reigning with righteousness there are none who come for judgment; the bustle has ceased, and the Hall of Justice will have to be closed. It behoves me, therefore, now to examine into my own faults; and if I find that anything is wrong in me, to put that away, and practise only virtue.”

Thenceforth he sought for some one to tell him his faults; but among those around him he found no one who would tell him of any fault, but heard only his own praise.

Then he thought, “It is from fear of me that these men speak only good things, and not evil things,” and he sought among those people who lived outside the palace. And finding no fault-finder there, he sought among those who lived outside the city, in the suburbs, at the four gates.[28] And there too finding no one to find fault, and hearing only his own praise, he determined to search the country places.

So he made over the kingdom to his ministers, and mounted his chariot; and taking only his charioteer, left the city in disguise. And searching the country through, up to the very boundary, he found no fault-finder, and heard only of his own virtue; and so he turned back from the outermost boundary, and returned by the high road towards the city.

Now at that time the king of Kosala, Mallika by name, was also ruling his kingdom with righteousness; and when seeking for some fault in himself, he also found no fault-finder in the palace, but only heard of his own virtue! So seeking in country places, he too came to that very spot. And these two came face to face in a low cart-track with precipitous sides, where there was no space for a chariot to get out of the way!
