How does Chapter 5 illustrate Sai Baba's principle of non-duality and his 'profound play'?

Chapter 5 masterfully illustrates Sai Baba's 'profound play' and the concept of non-duality through his interaction with the Fakir. After the Fakir returned repentant, Baba treated him with respect, maintaining the appearance that 'he is the Guru and I am the disciple.' This act is described as Baba's 'profound play,' a divine lesson in humility. The chapter connects this to the advanced state of a wise man who resides in non-duality, for whom the 'entire universe is his own form.' It argues that just as the sun cannot enter darkness, a wise man cannot possess a sense of duality. Baba’s conduct, as related by Mahalsapati in Chapter 5, shows him living this truth, operating beyond the dualities of pride, status, and karma, thereby teaching a lesson without explicitly preaching.
