Before the miracle with the water, what was Sai Baba's daily routine for lighting the lamps?

The source material in Chapter 5 describes Sai Baba's deep love for lighting lamps, noting he even celebrated the Diwali festival. His daily routine involved taking a tin pot in his hand and personally visiting the shops of the grocers and oil-merchants. He would beg for oil and use it to fill the lamps in both the temple and the mosque, which would then burn brightly. He even made his own wicks by tearing rags. This was his established practice for some time before the grocers decided to stop providing him with free oil.
