You did know of such a parable, didn't you?
It is a case, O Lord, as if a certain man went away from his father and betook himself to some other place. He lives there in foreign parts for many years, twenty or thirty or forty or fifty. In course of time the one (the father) becomes a great man; the other (the son) is poor; in seeking a livelihood for the sake of food and clothing he roams in all directions and goes to some place, whereas his father removes to another country. The latter has much wealth, gold, corn, treasures, and granaries; possesses much (wrought) gold and silver, many gems, pearls, lapis lazuli, conch shells, and stones(?), corals, gold and silver; many slaves male and female, servants for menial work. and journeymen; is rich in elephants, horses, carriages, cows, and sheep. He keeps a large retinue; has his money invested in great territories, and does great things in business, money-lending, agriculture, and commerce.
In course of time, Lord, that poor man, in quest of food and clothing, roaming through villages, towns, boroughs, provinces, kingdoms, and royal capitals, reaches the place where his father, the owner of much wealth and gold, treasures and granaries, is residing. Now the poor man's father, Lord, the owner of much wealth and gold, treasures and granaries, who was residing in that town, had always and ever been thinking of the son he had lost fifty years ago, but he gave no utterance to his thoughts before others, and was only pining in himself and thinking: I am old, aged, advanced in years, and possess abundance of bullion, gold, money and corn, treasures and granaries, but have no son. It is to be feared lest death shall overtake me and all this perish unused. Repeatedly he was thinking of that son: O how happy should I be, were my son to enjoy this mass of wealth!
Meanwhile, Lord, the poor man in search of food and clothing was gradually approaching the house of the rich man, the owner of abundant bullion, gold, money and corn, treasures and granaries. And the father of the poor man happened to sit at the door of his house, surrounded and waited upon by a great crowd of Brâhmans, Kshatriyas, Vaisyas, and Sûdras; he was sitting on a magnificent throne with a footstool decorated with gold and silver, while dealing with hundred thousands of kotis of gold-pieces, and fanned with a chowrie, on a spot under an extended awning inlaid with pearls and flowers and adorned with hanging garlands of jewels; sitting (in short) in great pomp. The poor man, Lord, saw his own father in such pomp sitting at the door of the house, surrounded with a great crowd of people and doing a householder's business. The poor man frightened, terrified, alarmed, seized with a feeling of horripilation all over the body, and agitated in mind, reflects thus: Unexpectedly have I here fallen in with a king or grandee. People like me have nothing to do here; let me go; in the street of the poor I am likely to find food and clothing without much difficulty. Let me no longer tarry at this place, lest I be taken to do forced labour or incur some other injury.
Thereupon, Lord, the poor man quickly departs, runs off, does not tarry from fear of a series of supposed dangers. But the rich man, sitting on the throne at the door of his mansion, has recognised his son at first sight, in consequence whereof he is content, in high spirits, charmed, delighted, filled with joy and cheerfulness. He thinks: Wonderful! he who is to enjoy this plenty of bullion, gold, money and corn, treasures and granaries, has been found! He of whom I have been thinking again and again, is here now that I am old, aged, advanced in years.
At the same time, moment, and instant, Lord, he despatches couriers, to whom he says: Go, sirs, and quickly fetch me that man. The fellows thereon all run forth in full speed and overtake the poor man, who, frightened, terrified, alarmed, seized with a feeling of horripilation all over his body, agitated in mind, utters a lamentable cry of distress, screams, and exclaims: I have given you no offence. But the fellows drag the poor man, however lamenting, violently with them. He, frightened, terrified, alarmed, seized with a feeling of horripilation all over his body, and agitated in mind, thinks by himself: I fear lest I shall be punished with capital punishment; I am lost. He faints away, and falls on the earth. His father dismayed and near despondency says to those fellows: Do not carry the man in that manner. With these words he sprinkles him with cold water without addressing him any further. For that householder knows the poor man's humble disposition I and his own elevated position; yet he feels that the man is his son.
The householder, Lord, skilfully conceals from every one that it is his son. He calls one of his servants and says to him: Go, sirrah, and tell that poor man: Go, sirrah, whither thou likest; thou art free. The servant obeys, approaches the poor man and tells him: Go, sirrah, whither thou likest; thou art free, The poor man is astonished and amazed at hearing these words; he leaves that spot and wanders to the street of the poor in search of food and clothing. In order to attract him the householder practises an able device. He employs for it two men ill-favoured and of little splendour. Go, says he, go to the man you saw in this place; hire him in your own name for a double daily fee, and order him to do work here in my house. And if he asks: What - work shall I have to do? tell him: Help us in clearing the heap of dirt. The two fellows go and seek the poor man and engage him for such work as mentioned. Thereupon the two fellows conjointly with the poor man clear the heap of dirt in the house for the daily pay they receive from the rich man, while they take up their abode in a hovel of straw in the neighbourhood of the rich man's dwelling. And that rich man beholds through a window his own son clearing the heap of dirt, at which sight he is anew struck with wonder and astonishment.
Then the householder descends from his mansion, lays off his wreath and ornaments, parts with his soft, clean, and gorgeous attire, puts on dirty raiment, takes a basket in his right hand, smears his body with dust, and goes to his son, whom he greets from afar, and thus addresses: Please, take the baskets and without delay remove the dust. By this device he manages to speak to his son, to have a talk with him and say: Do, sirrah, remain here in my service; do not go again to another place; I will give thee extra pay, and whatever thou wantest thou mayst confidently ask me, be it the price of a pot, a smaller pot, a boiler or wood, or be it the price of salt, food, or clothing. I have got an old cloak, man; if thou shouldst want it, ask me for it, I will give it. Any utensil of such sort, when thou wantest to have it, I will give thee. Be at ease, fellow; look upon me as if I were thy father, for I am older and thou art younger, and thou hast rendered me much service by clearing this heap of dirt, and as long as thou hast been in my service thou hast never shown nor art showing wickedness, crookedness, arrogance, or hypocrisy; I have discovered in thee no vice at all of such as are commonly seen in other man-servants. From henceforward thou art to me like my own son.
From that time, Lord, the householder, addresses the poor man by the name of son, and the latter feels in presence of the householder as a son to his father. In this manner, Lord, the householder affected with longing for his son employs him for the clearing of the heap of dirt during twenty years, at the end of which the poor man feels quite at ease in the mansion to go in and out, though he continues taking his abode in the hovel of straw.
After a while, Lord, the householder falls sick, and feels that the time of his death is near at hand. He says to the poor man: Come hither, man, I possess abundant bullion, gold, money and corn, treasures and granaries. I am very sick, and wish to have one upon whom to bestow (my wealth); by whom it is to be received, and with whom it is to be deposited. Accept it. For in the same manner as I am the owner of it, so art thou, but thou shalt not suffer anything of it to be wasted.
And so, Lord, the poor man accepts the abundant bullion, gold, money and corn, treasures and granaries of the rich man, but for himself he is quite indifferent to it, and requires nothing from it, not even so much as the price of a prastha of flour; he continues living in the same hovel of straw and considers himself as poor as before.
After a while, Lord, the householder perceives that his son is able to save, mature and mentally developed; that in the consciousness of his nobility he feels abashed, ashamed, disousted, when thinking of his former poverty. The time of his death approaching, he sends for the poor man, presents him to a gathering of his relations, and before the king or king's peer and in the presence of citizens and country-people makes the following speech: Hear, gentlemen! this is my own son, by me begotten. It is now fifty years that he disappeared from such and such a town. He is called so and so, and myself am called so and so. In searching after him I have from that town come hither. He is my son, I am his father. To him I leave all my revenues, and all my personal (or private) wealth shall he acknowledge (his own).
The difference between this parable and the Christian version is simply in this version, the son cultivates skills and transcends greediness through his experience, whereas the son in the Christian version gets "immediately forgiven" with no effort on his part. The former earns what is his birthright, the latter is reconciled to his father, but without material recompense.
Naturally I prefer the Buddhist version.
