What happened to Karnik when he visited the Kala Rama temple in Nashik?

According to Chapter 33, when a devotee named Karnik went for Darshan at the temple of Kala Rama in Nashik, he had an unexpected encounter. The saint Narsing Maharaj, who was there with his own devotees, suddenly got up, held Karnik by the wrist, and demanded, "Give my Rupee." Karnik was amazed but gave the Rupee with great joy, feeling as if Sai Baba himself was accepting the offering. The text describes this as a forceful acceptance, happening without Karnik even having time to contemplate it.
