Chhath Puja is one of India’s oldest and most profound festivals celebrating the bond between humans and nature. Observed across the country, it honours Surya, the Sun God, as the source of life and energy. For four days, devotees fast, pray, and stand knee-deep in water, offering arghya to the setting and rising sun. Across cities and villages, rivers and seas glow with countless diyas, creating one of the most moving sights in Indian culture.
