What does it mean when the text says Sai Baba is beyond birth and death and his body was just an 'adjunct'?

Chapter 43 explains that Sai Baba's true nature is that of the "complete Supreme Brahman," an eternal and formless reality. In this state, the concepts of birth and death are meaningless. The physical body he inhabited is described as merely an "adjunct," a temporary vessel or tool he used for the sake of his devotees' salvation. The text emphasizes that for him, who is a "mass of bliss," there is no consciousness of the body, and therefore no physical or mental illness in the way humans experience it. His departure was a conscious choice to release this adjunct and merge back into his "previous unmanifest state," transcending the material form entirely.
