According to Chapter 43, what was Sai Baba's state of being after he left his physical form?

Chapter 43 explains that after leaving the body, Sai Baba reached an incomprehensible and imperishable state, a dwelling of happiness devoid of rebirth. The author describes this transition as moving from a manifest form to an unmanifest one. By shedding his physical body, his localized nature ended, and he achieved omnipresence. The chapter states that he became eternally whole, merging with his true self. Though the one-sided avatar ended, his complete form was realized, and he remained the life and soul of all, just in a non-physical, all-pervading way.
