I've heard Baba gave complex philosophical discourses. Can you describe the content of his afternoon lectures and how he explained the Upanishads?

According to the information available in Chapter 0, the premise that Maharaj gave complex philosophical discourses on subjects like the Upanishads is incorrect. The text explicitly states that Maharaj did not openly explain profound Vedanta subjects. Instead, his advice was primarily ethical. He held three general sittings per day where he would give advice through stories, often tailored to address matters on the minds of the people present. The purpose of this ethical guidance was to purify the disciple's ground, preparing them for deeper knowledge later, which aligns with the traditional Sadguru's practice.
