Given that the text mentions a group of devotees and various deities in the opening invocation, does it provide any connection between them and Gajanan Maharaj?

The provided text from Chapter 29 does not establish any connection to Gajanan Maharaj. The chapter opens with traditional invocations to Shri Ganesh, Shri Saraswati, and others. It then describes a group of devotees from the Ramdasi sect visiting Shirdi. However, the narrative exclusively focuses on their interaction with Sai Baba and his divine qualities of generosity and compassion. As explored in Chapter 29, while verse 8 uses the term 'Maharaj,' this is a title for Sai Baba himself. No link, explicit or implicit, is made to Gajanan Maharaj in these verses.
