According to the scripture, was Sai Baba's physical body his true form, and what is his ultimate essence?

Chapter 43 emphatically states that Sai Baba's physical body was not his true form but merely an 'adjunct.' It challenges the notion of him being limited to a body of 'three and a half cubits.' His ultimate essence is described as the 'complete Supreme Brahman,' beginningless, endless, and unmanifest. The text explains that it is improper to confine him to a specific caste or form, as he is 'beyond death' and 'essentially beyond the womb.' His physical manifestation was a voluntary incarnation taken for the welfare of people, and upon the completion of this task, he merged back into his true, unmanifest form, from which he continues to fill the entire 'moving and non-moving world.'
