How does the scripture explain the concepts of birth and death, particularly in relation to great Yogis like Sai Baba?

Chapter 43 provides a profound philosophical explanation. It defines birth as the union of body and senses, and death as their separation. However, for a great Yogi like Sai Baba, these are considered false imaginations. The text posits that death is a characteristic of the soul's nature, but saints 'place their feet on the head of Time.' For Sai, who is a 'mass of bliss' and the 'complete Supreme Brahman,' there is no birth or death. He is devoid of bodily impulses, and his apparent departure was a voluntary act of merging into the unmanifest by burning the body in the fire of Yoga.
