How does the text explain the difference between death for a normal person and for a perfected Yogi like Sai Baba?

Chapter 43 draws a sharp distinction between ordinary death and the state of a perfected Yogi. For most, death is the separation of body and senses, an event tied to birth. For a saint who has conquered mortality, death is described as an illusion or 'like dust.' The text uses the analogy of a solar eclipse, which is not the end of the sun but merely a 'defect of vision.' For Sai Baba, who is the Supreme Brahman, the body is just an adjunct. His leaving the body was a 'spontaneous play of Yoga,' a willed act to merge into the unmanifest, not a submission to mortality.
