Can you tell me about the time a serpent appeared in Shirdi? I heard something about it in a barn.

Yes, there is a fascinating story about a serpent that entered a barn, causing panic among everyone present. However, a devotee named Balaji Nevasakar fearlessly placed a vessel full of milk before it. As detailed in Chapter 35, the serpent drank the milk and then vanished, eluding everyone's sight. While most people were relieved, Nevasakar was a bit disappointed because he wished to see the serpent as it departed, just as he had seen it arrive. This incident showcases the unique nature of Sai's leelas and the faith of his devotees.
