Chhath Puja is one of the most sacred and spiritually meaningful festivals celebrated in India, particularly in Bihar, Jharkhand, eastern Uttar Pradesh, and parts of Nepal. Dedicated to the Sun God, Surya, and Chhathi Maiya, the festival is observed with great devotion, discipline, and faith. Unlike many other Hindu festivals, Chhath Puja involves elaborate rituals performed near rivers, ponds, and other water bodies, where devotees offer prayers to the setting and rising Sun.
