Did Sai Baba primarily teach complex philosophy, or was his approach different?

According to the source material, Maharaj's approach was not to openly explain profound Vedanta subjects or give discourses on the Upanishads. His advice was primarily ethical. Chapter 0 explains that this was a deliberate method, following the Sadguru's scriptural practice of first purifying the disciple's ground and then sowing the seed of knowledge. While his verbal advice was focused on general ethical principles, the text emphasizes that the advice received from him in the form of direct experience was considered infinitely more valuable and brought the highest benefit to devotees who approached him with faith.
