What comparison is made in Chapter 42 between the anniversaries of gods and the anniversaries of saints?

In the context of describing the day of Sai Baba's Mahasamadhi, the text draws an interesting distinction between how gods and saints are commemorated. Chapter 42 notes that while that particular day was Buddha Jayanti (birth anniversary) for some, for Sai it became his Punya Tithi (death anniversary). The text then offers a general aphorism to explain this: "The birth anniversary of gods is the death anniversary of saints." This suggests that while deities are celebrated for their divine birth, great saints are venerated on the day they leave their mortal bodies and merge with the absolute.
