Can you describe what happened when the darveshis brought the sick tiger to Sai Baba?

Certainly. The incident, as detailed in Chapter 31, was quite dramatic. A group of darveshis brought a fierce, diseased, and restless tiger to Shirdi. After getting Baba's permission, they brought the creature before him, holding its chain tightly. Upon seeing Sai's radiant form, the tiger was visibly startled and bowed its head with reverence. As Sai gazed upon it with a loving heart, the tiger struck its tail on the ground three times, placed its body at Sai's feet, let out one final terrifying roar, and died. The onlookers were all 'struck with wonder' at this miraculous and sudden passing.
