Could you detail the specific ritual-like steps Baba took to perform the miracle with the lamps and water?

Certainly. The process, as detailed in Chapter 5, was very specific. After the grocers refused him oil, Baba returned to the mosque. He first picked up his tin pot, which contained only a tiny amount of oil. He then poured water into that pot with the bit of oil and proceeded to drink the mixture himself, making it an 'offering to Brahman.' Following this act, he took plain water and poured that into the lamps, ensuring the dry wicks were completely soaked. Finally, he lit the water-soaked wicks with a match, and they miraculously burned throughout the night.
