UP is organizing Mahakumbh and expected to get billions of revenue. Can Bihar organise events at such scale ?

Bihar is the centre of Buddhism, where they gather every 100 years for Baudh Sangiti. It's the birthplace of Devi Seeta, Walmiki. We have many Shakti peeth and other famous temple including the world oldest Mundeswari temple. Don't even forget about world famous Chhath puja. Can we organise memorable events at such scale?
