Durga Puja in Bihar is a grand celebration, blending tradition, devotion, and festivity. It typically spans five days, from Shashthi to Dashami, marking the victory of Goddess Durga over the demon Mahishasura. The festival is marked by vibrant pandals, elaborate idols, and cultural performances. Major cities like Patna, Gaya, and Bhagalpur host grand processions and fairs. Devotees perform rituals, offer prayers, and participate in bhajans and aarti. The festival culminates with the immersion of idols in rivers, symbolizing the goddess’s return to her heavenly abode, while families come together to celebrate joyfully.
