I'm seeking profound philosophical teachings. Did Baba give open discourses on the Upanishads or Vedanta?

According to the information provided in Chapter 0, Maharaj's approach was not to openly explain profound Vedanta subjects or give discourses on the Upanishads. His advice was primarily ethical in nature. The text explains that his method, like that of a Sadguru, was to first purify the disciple's 'ground' with these ethical principles before sowing the 'seed of knowledge.' Therefore, while his ultimate goal was salvation, his direct verbal teachings focused on foundational ethics rather than complex philosophical exegesis, with deeper lessons being conveyed through experience.
