Based on the descriptions in the scripture, what was Sai Baba's nature like and what does it teach devotees about the spiritual path?

Chapter 37 describes Shri Sai Baba's nature as incomprehensible, marvelous, and profound. His state was unpredictable; He was sometimes seen intoxicated with Brahmananda (the bliss of the Self) and at other times appeared completely detached from all activity. Though He might seem inactive, He was always alert, with His mind fixed on Self-realization. For devotees, this teaches that the ways of a Satguru are beyond ordinary understanding. His life shows that the spiritual path involves cultivating unwavering devotion, increasing one's spirit of service, and learning to see Divinity in all beings. The goal, as expressed in the chapter, is for this devotion and wisdom to remain steady and unshakable, guiding us through life.
