How does the text differentiate between the experience of death for an ordinary person versus a saint like Sai?

The text in Chapter 43 draws a sharp distinction. For most, death is the end of worldly life. For a saint, however, worldly life ends but spiritual attainment remains, and the feeling of duality completely vanishes. Chapter 43 explains that saints are free from the six-fold emotions and exist in an unmanifest state, only becoming manifest for the salvation of their devotees. They view birth and death as false imaginations. While an ordinary person experiences death as the separation of body and senses, for a saint like Sai, who is identified with the Supreme Brahman, the concepts of birth and death do not apply at all.
