How does the text explain Sai Baba's true essence, distinguishing it from his physical body?

Chapter 43 describes Sai Baba's true essence as being far beyond his physical form. He is referred to as 'Sai Samarth is a mass of bliss' and the 'complete Supreme Brahman.' In this state, concepts like birth and death are irrelevant. The text clarifies that due to the truth of Brahman, the world is an illusion, and for someone like Sai, there is no consciousness of the body. His physical actions, like holding or releasing his breath, were considered the spontaneous play of Yoga for the salvation of his devotees. His body was merely an adjunct, and he was devoid of bodily impulses and the associated mental or physical illnesses.
