According to Chapter 43, what was Sai Baba's state after he left his physical body, and how did this transformation affect his nature?

Chapter 43 explains Sai Baba's post-mortem state as a profound transformation rather than an end. It describes him as reaching an "imperishable state, devoid of rebirth" and merging with his true self. The chapter contrasts his previous manifest form, where he was localized by wearing a body, with his new unmanifest state where he "lost his localized nature and reached omnipresence." By leaving his body, his "one-sided avatar ended," but his "complete form was beautifully realized." He became eternally whole, the life and soul of all, performing the process of departure by his own hand.
