How does the text describe the true, formless nature of Sai Baba, beyond his physical body?

Chapter 43 delves into the transcendent nature of Sai Baba, describing him as the 'complete Supreme Brahman' and a 'mass of bliss,' for whom the physical body was merely an adjunct. The text asserts that it is improper to limit him to a specific caste or form, as his true self is beginningless and endless, destined to remain 'unbroken even at the end of the universe.' He is depicted as being beyond mental or physical illness and unaffected by the eight great Siddhis (yogic powers), as he himself is of 'unbroken prosperity.' This divine consciousness, firmly imprinted in the hearts of devotees, is his true form, which can never be said to have perished.
