When they capture the hawk in the wilds, they secure it neck and feet; they quickly cover up both its eyes and proceed to teach it to hunt. The hawk becomes accustomed and habituated to the strangers, and shuts its eyes upon its old associates; it is content with little food and thinks no more of what it used to eat. The falconer then becomes its attendant, and allows it to look out of one corner of an eye, so that
it may only see himself, and come to prefer him before all others. From him it takes all its food and drink, and sleeps not for a moment apart from him. Then he opens one of its eyes completely, and it looks contentedly, not angrily, upon him; it abandons its former habits and disposition, and cares not to associate with any other. And now it is fit for the assembly and the hand of kings, and with it they grace the chase. Had it not suffered hardship it would still have been intractable, and would have flown out at everyone it saw.
Others are heedless,--do thou be wise, and on this path keep thy tongue silent. The condition laid on such an one is that he should receive all food and drink from the Causer, not from the causes. Go, suffer hardship, if thou wouldst be cherished; and if not, be content with the road to Hell. None ever attained his object without enduring hardship; till thou burn them, what difference canst thou see between the willow and aloes wood?
