Why is Sai Baba considered to be beyond physical ailments and the limitations of the body?

As detailed in Chapter 43, Sai Baba is the complete Supreme Brahman, and due to the truth of Brahman, the world is seen as an illusion. For such a being, the consciousness of the body is non-existent. The body is described as merely an adjunct, and therefore mental or physical illnesses have no hold over them. Even if any ailments were to arise due to past karma, the text states that enlightened beings have no awareness of them. For Sai Samarth, who is a mass of bliss and does not know the birth of the body, there can be no real death or suffering for that body.
