How does Chapter 43 describe Sai Baba's state and existence after he left his physical body?

According to the descriptions in Chapter 43, after Sai Baba left his body, he transitioned from a manifest to an unmanifest state, achieving an imperishable existence devoid of rebirth. The chapter explains that while his 'one-sided avatar' ended, his complete form was realized as he lost his localized nature and attained omnipresence. He became eternally whole by merging with his true self. The text beautifully states, 'Sai was the life of all; Sai was the soul and breath of all.' In essence, as Chapter 43 portrays, he moved from being a physical presence in one location to being a spiritual presence everywhere, forever.
