How did the shopkeepers react after they refused to give Sai Baba oil and then witnessed him light lamps with water?

As described in Chapter 5, the grocers' reaction was one of profound shock and immediate repentance. After conspiring to refuse Baba oil, they watched to see what he would do. When they witnessed the lamps burning brightly with only water, they were so amazed they "put their fingers in their mouths." They instantly realized they had done something wrong by lying to Baba. The text states that the grocers began to tremble, feeling deep repentance for the sin of their untruth and for causing Baba needless trouble. The miracle of the lamps burning all night without oil powerfully highlighted Baba's spiritual stature and their own transgression.
