I heard Balaram Mankar was cured of asthma by Baba. Did he ever experience any symptoms again after that?

Yes, but in a very mysterious and significant way. After being miraculously cured of his six-year-long asthma by smoking Baba's chillim, Balaram remained completely healthy. However, Chapter 51 recounts a peculiar incident where he had a single, sudden fit of coughing one day. Everyone was amazed, but upon later inquiry, they learned the profound reason: this coughing fit occurred on the very day that Sai Baba gave up His physical body. It was understood to be a final, poignant sign from Baba to his devotee. After that day, Balaram never had a cough again for the rest of his life.
