What was Sai Baba's special routine related to the festival of lights?

Sai Baba had a great fondness for the festival of lights and maintained a dedicated routine to celebrate it. As detailed in Chapter 5, he would personally take a tin pot and go to the shops of grocers and oil-merchants to beg for oil. He used this oil to light lamps and ensure they burned brightly in both the temple and the mosque. This was a daily practice for some time. The text highlights his love for this activity by mentioning that he even celebrated the Diwali festival by tearing rags to make wicks for the lamps he lit in the mosque.
