What was the reaction of the grocers after witnessing Baba light the lamps with water?

The grocers' reaction was one of immediate shock and subsequent repentance. As described in Chapter 5, upon seeing the water burn like oil, they 'put their fingers in their mouths' in amazement. They quickly realized their wrongdoing, acknowledging to themselves that they had sinned by lying to Baba and causing him needless trouble. The text states that these grocers, who became 'unworthy of Sai’s grace' through their actions, began to tremble and felt deep repentance for their wicked conspiracy.
