According to the text, how should we understand the concept of death, especially in the context of a great saint like Sai Baba?

The text explains that death is merely the separation of the body and senses, a natural characteristic of the soul's nature. For a great Yogi like Sai Samarth, who is described as the complete Supreme Brahman, physical death is an illusion. As Chapter 43 clarifies, he is devoid of bodily impulses, and for him, the world itself is an illusion. His departure is compared to a solar eclipse, which is just a defect of vision. He did not truly perish but simply burned his physical form in the fire of Yoga to merge back into his unmanifest state, continuing to reside in the hearts of his devotees.
