Can you tell me the story of the tiger that died in front of Sai Baba?

Of course. Chapter 31 recounts how some darveshis brought a fierce and diseased tiger before Sai Baba. Upon seeing Baba's radiant form and meeting his gaze, the tiger was startled and bowed its head with reverence. It then raised its tail, struck the ground three times, and fell motionless at Sai's feet, dying instantly. The onlookers were struck with wonder at this event. The darveshis, though initially sad about losing their livelihood, were also pleased because they understood the creature had attained liberation by leaving its body in the presence of a saint.
