I heard Sai Baba's Mahasamadhi happened on a day that was significant for multiple religions. What does Chapter 42 say about this?

Yes, Chapter 42 confirms the confluence of several significant dates on the day of Sai Baba's passing. The primary day mentioned is Vijayadashami, a major Hindu festival also known as Dussehra. In addition to this, the chapter explicitly states that the day corresponded to the 9th day of the Muslim month, which is the eve of Moharram, referred to as the night of 'Kattal'. Adding another layer of significance, the text also makes a point to mention that for some people, this same day was observed as Buddha Jayanti. This highlights a remarkable convergence of important occasions from different spiritual traditions.
