According to the text, where was Nana Chandorkar when he received the message about the sick girl, and what was his immediate action since he had no Udi?

As the narrative in Chapter 33 explains, Nana Chandorkar was at the Thane city station while on his way to Kalyan with his family. It was there that a message reached him from a devotee whose daughter was suffering from glandular fever and was in need of Prasad Udi. Finding himself without any Udi on hand, Nana's immediate action was one of pure faith. He picked up clay from the road, stood right there, and offered prayers to Sai the Almighty. He then applied a pinch of this consecrated clay, demonstrating that the power of prayer and faith in Sai was the essential component for the healing to occur, even more so than the physical Udi itself.
