What was the significance of Lonavala in the relationship between Nana Chandorkar and Kakasaheb Dixit? Did they have business dealings there?

The text does not mention any business dealings between Nana Chandorkar and Kakasaheb Dixit in Lonavala. Instead, it points to a conversation in Lonavala as a pivotal moment in Dixit's spiritual journey. As explained in Chapter 51, the meeting and conversation with Nana in Lonavala was the 'seed-sowing of this attraction towards Baba as a Guru' for Dixit. This earlier event is mentioned to provide context for Dixit's immense joy upon receiving Baba's portrait and the subsequent coincidences on his journey to Shirdi, including unexpectedly meeting Nana Chandorkar again at the Kopergaon station. The focus is purely on the spiritual connection fostered there, not on any worldly affairs.
