What was the nature of Sai Baba's teachings, and did he lecture on complex spiritual texts?

Sai Baba's teachings were not complex philosophical discourses on texts like the Upanishads. Instead, his advice was primarily ethical. As explained in Chapter 0, his method was to first purify the disciple's ground with general ethical principles before planting the seed of deeper knowledge. This followed the traditional scriptural practice of a Sadguru. The text emphasizes that the advice received from him through direct experience was considered infinitely more valuable than his verbal teachings, leading to the highest benefit for devotees who approached him with faith.
