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

According to Chapter 43, Sai Baba's physical death was a transition into a higher state of being, not an end. The text explains that by leaving his body, he moved from being manifest to unmanifest. He shed his localized nature to achieve omnipresence, becoming "eternally whole, merging with his true self." This is described as reaching an "imperishable state, devoid of rebirth" and a "dwelling of happiness." While his physical avatar's journey ended, his complete form was realized. This transformation is presented as a joyful union, or Sayujya, where he became the life and soul of all, even as his physical absence caused great lamentation among his followers.
