Can you provide details from Chapter 29 on Sai Baba's teachings about Advaita Vedanta philosophy to the visiting devotees?

The provided excerpts of Chapter 29 do not contain any details about Sai Baba giving specific philosophical teachings on Advaita Vedanta. The chapter focuses on his actions and character rather than his verbal discourses. It describes his "incomprehensible wisdom" and "unfathomable divine play," his generosity in distributing money, and his interactions with a group of devotees from the Ramdasi sect who performed devotional singing. According to Chapter 29, the focus is on his charitable nature and unpredictable manner, not on specific philosophical lectures.
