A padshah entrusted a tutor with the care of his son, saying: ‘This is thy son. Educate him as if he were one of thy own children.’ He kept the prince for some years and strove to instruct him but could effect nothing, whilst the sons of the tutor made the greatest progress in accomplishments and eloquence. The king reproved and threatened the learned man with punishment, telling him that he had acted contrary to his promise and had been unfaithful. He replied: ‘O king, the instruction is the same but the natures are different.’

Although both silver and gold come from stones
All stones do not contain silver and gold.
Canopus is shining upon the whole world
But produces in some places sack-leather and in others adim.
