Historical and Scriptural Background

The history of Chhath Puja is as ancient as Vedic culture itself. The Vedas contain numerous mantras in praise of Surya Dev, where Sun worship is described as the foundation of life, health, and prosperity. Ancient scriptures and Puranas also mention Goddess Shashthi or Chhathi Maiya, who is associated with the blessings of children and protection of life.
It is believed that during the Mahabharata era, Karna, the son of Surya Dev, worshipped the Sun daily, and this tradition gradually evolved into Chhath Puja. According to the Ramayana, Mata Sita also observed this fast. These accounts clearly indicate that Chhath Puja was never limited to a particular region; rather, it has deeply rooted itself in Indian culture.
The festival is most popular in Bihar, Jharkhand, eastern Uttar Pradesh, and Nepal’s Terai region. However, today Indians across the country and abroad observe the vrat with the same devotion.


The Four Sacred Days of Chhath Puja

Chhath Puja spans four days, and each day holds its own significance and set of rules. Every phase of the fast is filled with spiritual joy.

1. Nahay-Khaye

On the first day, the devotee takes a bath before sunrise in a sacred river or pond such as the Ganga or Yamuna. This is followed by thorough cleaning of the house and purification of the kitchen. The devotee eats only once on this day, a meal known as “Nahay-Khaye.” This food is completely sattvic and prepared with utmost purity.
The purpose of this day is to purify the body, home, and mind and prepare oneself for the fast.

2. Kharna

The second day is known as “Kharna” or “Lohanda.” On this day, the devotee observes a strict day-long waterless fast (nirjala). After sunset, the devotee consumes a prasad made of jaggery-sweetened kheer, roti, and bananas.
From this point onward, the devotee observes a continuous 36-hour fast without consuming even water. This phase is extremely challenging and is completed with deep devotion and remarkable willpower.

3. Sandhya Arghya

On the third day, devotees offer the first Arghya to the setting sun. This ritual creates a divine and mesmerizing atmosphere. The riverbanks and lakes glow with thousands of lamps, colorful attire, and devotional songs. Devotees carry bamboo baskets filled with fruits, thekua, coconuts, and other offerings for Surya Dev. Traditional folk songs sung by women enhance the sacredness of the moment.

4. Usha Arghya

On the fourth and final day, the devotee offers Arghya to the rising sun. This moment marks the pinnacle of the vrat. With the first rays of dawn, devotees pray for the well-being, prosperity, and health of their families. After offering the Arghya, they consume prasad and conclude the fast.

Rules of Purity and Devotion

The core foundation of Chhath Puja is purity—of the body, mind, and environment. Devotees follow these rules with complete sincerity.

  • Purity of Food:
    All meals prepared for the devotee must be sattvic. Onion, garlic, meat, and alcohol are strictly prohibited. Food is prepared at home using pure water and clean earthen or copper vessels.
  • Environmental Cleanliness:
    The area of worship must be kept spotless. The water of the river or pond should be clean, and all offerings must be natural and organic.
  • Purity of Mind:
    The devotee must avoid anger, greed, jealousy, and falsehood. The mind should be filled only with devotion and faith.
  • Fasting Discipline:
    The 36-hour nirjala fast after Kharna is the toughest part of Chhath Puja. It is not just physical discipline but also a form of mental austerity.
