Describe Ramchandra Dada Patil's near-death experience and the specific prophecy Sai Baba gave him during that encounter.

Ramchandra Dada Patil was suffering from an unbearable illness and had become completely dejected, tired of life. As recounted in Chapter 42, Sai Baba appeared in a vision at his bedside one night. When Patil pleaded to know when his death would come, Baba, the embodiment of compassion, reassured him, saying, "Your danger to life (Gandantara) has passed... your 'Hundi' (bill of exchange/life span) has been fully returned." After saving Ramchandra, Baba delivered a grave prophecy, stating he did not see a good fate for Tatya. He foretold that Tatya would pass away on Vijayadashami in the Shaka year 1840, an event that would unfold in a truly mysterious fashion.
