How did Narayanrao's faith in Sai Baba develop and become unshakeable?

Narayan Motiram Jaani's faith in Sai Baba grew through direct, personal experience. As detailed in Chapter 33, Baba advised him to quit his service job and start his own business. Narayanrao followed this instruction, leaving his job and establishing "Anandashram." The business prospered, and its success brought him peace of mind. The text explicitly states, "Seeing such developments, faith in Sai's feet increased; that then developed into the form of firm devotion; through experience it became unshakeable." This demonstrates that his faith was not blind but was fortified by witnessing the truth and positive outcome of Baba's words in his own life.
