What caused Baba's sudden and terrifying outburst when the paving work began in the Masjid courtyard?

According to Chapter 13, the paving work in the Masjid courtyard began with the strike of a pickaxe. The sound of this strike alone triggered a dramatic and frightening reaction from Baba. He immediately became furious, assuming a 'Narasimha avatar' with terrifyingly glaring eyes. He grabbed his Satka (stick) and shouted, 'Who is striking the pickaxe? I will hang him by his waist!' This intense outburst caused widespread fear, making the laborer and others flee. Baba's reaction was so sudden and powerful that it startled everyone present, including Kaka Mahajani.
