What role does the physical body play for a Yogi like Sai Baba, as described in the text?

As detailed in Chapter 43, the physical body for a perfected Yogi like Sai Baba is considered 'merely an adjunct.' He is described as being 'devoid of bodily impulses' and lacking consciousness of the body, indicating a profound detachment from the physical form. The text suggests that even if physical or mental illnesses were to arise due to past karma, the Yogi would have 'no awareness of them.' Death is presented as the nature of the body, even a state of happiness for it, but for Sai, who is the Supreme Brahman, the body itself is part of an illusion. His departure was a conscious release of this adjunct to merge back into his true, unmanifest state.
