Can you tell me about Karnik's experience with a saint in Nashik and how it relates to Sai Baba?

According to chapter 33, a devotee named Karnik traveled to Nashik and visited the temple of Kala Rama. While there for Darshan, he had an unexpected encounter with the saint Narsing Maharaj. Amidst a circle of devotees, the saint suddenly grabbed Karnik's wrist and demanded, "Give my Rupee." Although amazed, Karnik gave the Rupee with great joy, feeling as though Sai Baba himself was the one accepting the money. The text describes this as a powerful moment, suggesting the Rupee was taken by force rather than merely accepted, illustrating how Sai can work through other saints to interact with his devotees.
