Why shouldn't devotees feel sorrow over Sai Baba's physical departure, according to Chapter 43?

Chapter 43 explains that for saints who are perpetually happy in the bliss of Brahman, the end of the physical body does not bring sorrow or grief, as this is its natural state. Saints like Sai manifest in a physical form for the salvation of their devotees, and their worldly life ending is part of this divine purpose. The feeling of duality vanishes for them as they are filled with their true form. The text encourages listeners to understand that what we perceive as 'death' for a saint is an illusion, much like a solar eclipse is a defect of our vision, not the end of the sun. Their spiritual attainment remains, and they are always present, free from the body which is merely an adjunct.
