What were the exact details of Sai Baba's prophecy about Tatya's death, and how was this secret managed by those who knew?

The prophecy Sai Baba made was remarkably specific. According to the account in Chapter 42, Baba told Ramchandra Patil, "In the Shaka year 1840, in the month of Ashvin, in the bright half during Vijayadashami, Tatya will attain the eternal state." Recognizing the distress this news would cause, Baba explicitly instructed Ramchandra, "But do not speak of this to him; he will lose heart." The secret was carefully managed. Ramchandra, though burdened, kept it from Tatya. However, he did confide in one other person, whispering it into the ear of Bala Shimpi, with the same request not to tell anyone else. Both Ramchandra and Bala Shimpi were gripped by worry as they held this secret for the two years leading up to the prophesied event.
