Explain the context of the phrase 'the birth anniversary of gods is the death anniversary of saints' within Chapter 42.

This profound statement appears in Chapter 42 within the detailed narration of the day Sai Baba left his body. The text meticulously records the date as Vijayadashami in the Shaka year 1840. In this context, the author notes that for some people, that particular day was also Buddha Jayanti. The author then inserts the aphorism, 'The birth anniversary of gods is the death anniversary of saints,' to draw a powerful spiritual parallel. It suggests that the departure of a great saint from the mortal world is an event of such cosmic significance that it should be viewed with the same reverence and celebration as the birth of a deity, thus elevating the Punya Tithi to a sacred festival.
