Can you recount the story of the diseased tiger that was brought before Sai Baba?

Certainly. As detailed in Chapter 31, a group of darveshis brought a fierce, diseased, and restless tiger before Sai Baba. They held its chain tightly as they presented the animal to Him. Upon seeing the radiant Sai, the tiger was startled and bowed its head with reverence. As their eyes met, Baba gazed at the tiger with a loving heart. The tiger then struck its tail on the ground three times, placed its body at Sai's feet, gave one terrifying roar, and immediately died. The onlookers were struck with wonder at this miraculous event, seeing the creature attain liberation at the feet of a saint.
