According to Chapter 43, what was the spiritual significance of Sai Baba leaving his physical body?

Chapter 43 explains that Sai Baba's departure was a transition from a manifest to an unmanifest state. By leaving his body, he transcended his localized nature and achieved omnipresence. The text describes this as reaching an imperishable state devoid of rebirth, where he became eternally whole by merging with his true self. While his one-sided avatar form ended, his complete form was realized. This transformation is presented not as an end, but as attaining a state of self-attainment and a dwelling of happiness, a process that saints perform by their own will, igniting their own light to burn their own bodies.
