Crowds at the Nellore Rottela Panduga swelled on the second day, with even higher numbers expected for the main Sunday event.
The signature ritual of exchanging 'wish rotis' remains the primary attraction, with many seeking blessings for children, health, and employment.
The state government has invested Rs 25 crore total in infrastructure for the festival, including plans for a new prayer hall.
Enhanced security includes 24/7 drone surveillance and strict crowd management protocols overseen by senior police officials.
