21.1.5

In this hunt I, in order to ascertain the fact, released several antelopes of handsome appearance and strong bodies, before they had received any wounds from teeth or claws, and ordered them to be kept in my presence, and that they should be taken the greatest care of. For a whole day and night they remained at ease in their natural conditions : on the second day a change was observed, and they threw about their legs as if they were drunk, without any reason, and fell down and rose up. However much tiryāq-i-fāruqī (preparation of opium) and other suitable medicines were administered to them, they had no effect, and when one watch had passed in this condition, they died. On this day the bad news arrived that the eldest son of Shah Parwiz had died at Agra. As he was somewhat grown-up, and was very attached and affectionate towards his father, the latter was exceedingly grieved and wounded at heart at this event, and great bewilderment and weakness manifested themselves in him. In order to console and please him, I sent him gracious letters, and covered over the deadly wound of his heart with the balm of affection and kindness, I hope that God, the great and glorious, may grant him patience and resignation, for in this kind of calamities there can be no better driver away of grief than endurance and resignation.
