Can you explain what it means when the text says Baba 'merged himself into the unmanifest' but also 'enjoys the state of his true self'?

This describes a profound yogic and metaphysical state. According to chapter 43, "merging into the unmanifest" signifies that Sai Baba, through his yogic power, voluntarily transcended his physical form to unite with his true nature as the formless, beginningless, and endless Supreme Brahman. This is his previous, original state. However, this is not a state of nothingness. The text clarifies that even in this unmanifest state, he "enjoys the state of his true self" and actively "keeps the devotees awake." This suggests that he retains his divine consciousness and ability to interact with and guide his followers, even without a physical body.
