How did Sai Baba's presence continue to be felt even after he attained Nirvana?

The text explains that even after Sai Baba attained Nirvana, his presence remained steadfastly available to his devotees. Chapter 33 clarifies that being in Samadhi is not the same as being dead, as Sai is beyond birth and death. The text uses the beautiful analogy of fire hidden in wood, which is not visible but is contained within and can be manifested through friction. Similarly, Sai Baba's presence becomes manifest for his devotees when they call on him with exclusive, undivided love. An example of this is the story of Narayanrao, who, three years after Baba's Samadhi, was gravely ill. He meditated on Baba day and night and was granted a dream vision where Sai came from an underground chamber and assured him of his recovery, which then came to pass, demonstrating that Baba continues to respond to the calls of his followers.
