October / November (Kartika) & March / April (Chaitra)

Chhath Puja (The Rigorous Four-Day Vedic Sun Worship & Environmental Tapasya)

Kartika (Shukla Paksha) [Primary] & Chaitra (Shukla Paksha) [Secondary] · Kartika Shukla Shashti (6th Waxing Lunar Day of Kartika) · Sharad / Hemanta Ritu (Late Autumn / Early Winter)

Occurs six days after Diwali on the 6th lunar day (*Shashti Tithi*) of Kartika. At this celestial juncture, solar radiation (*Surya-Rashmi*) undergoes a unique atmospheric refraction during sunset and sunrise. Standing in natural water bodies allows the human system to directly absorb therapeutic solar cosmic energy (*Pranic/Solar Electro-Magnetic Spectrum*), purifying the nervous system and destroying latent pathogens.

Sanatana & philosophical depth

Advaita And Non Duality

Worship Of The Setting Sun

Chhath Puja is unique in world literature for worshiping the setting Sun (*Sandhya Arghya*) before the rising Sun (*Usha Arghya*). In Vedantic thought, honoring the setting Sun symbolizes accepting life's inevitable declines, aging, and dissolution with equanimity (*Samatvam*), recognizing that decay is merely the necessary twilight before spiritual rebirth.

Purest Priestless Tapasya

Chhath Puja requires no intermediary priest (*Purohit*); the devotee (*Vrati*) directly faces the visible Supreme (*Pratyaksha Brahman*) in open nature. This embodies the purest Vedantic principle of direct, unmediated Self-communion (*Aparoksha Anubhuti*) and absolute physical purity.

Subtle Symbolism Of Bamboo Soop And Thekuwa

Eco Purity And Soop

All offerings are presented in eco-friendly woven bamboo baskets (*Soop/Daura*). Bamboo symbolizes adaptability, hollow selfless receptivity, and rapid spiritual growth.

Thekuwa As Sattvic Prasad

The core offering *Thekuwa* (whole wheat flour, jaggery, ghee, dried coconut, and cardamom molded with wooden stamps) represents pure, unadulterated *Sattvic* food cooked over natural wood fires on dedicated clay stoves, untouched by commercial processing.

Pauranik And Vedic Origins

Rigvedic Solar Hymns

Rooted directly in the Rigveda (*Surya Suktam*), where Rishis worshiped the Sun through water libations (*Arghya*) during dawn and dusk to attain mental brilliance (*Dhi*) and spiritual vitality.

Sita Mata And Drapuadi Tapasya

According to local traditions, Goddess Sita performed Surya Shashti Vrat at Munger upon returning to Ayodhya after exile, while Draupadi observed Chhath to restore the Pandavas' lost kingdom and health.

Subtle body & chakras

Solar Retinal Absorption And Pineal Activation

Standing waist-deep in flowing natural water while gazing gently (*Trataka*) at the setting/rising solar disk neutralizes static bodily electricity and activates the Ajna (Third Eye) and Pineal Gland. Water acts as a natural conductor, allowing solar Prana to flow through the soles of the feet directly up the Sushumna Nadi.

36 Hour Nirjala Pranayama

The 36-hour waterless fast (*Nirjala Vrat*) purifies the digestive fire (*Jatharagni*), burns away deep subconscious karmic impressions (*Samskaras*), and converts physical energy into refined spiritual Ojas.

Meditative techniques

Stages of realization

1. Nahay Khay (Bodily & External Purification)

Bathing in sacred rivers, thoroughly scrubbing the residence, and partaking in a single Sattvic meal (bottle gourd and chana dal cooked in rock salt) to detoxify the physical sheath (*Annamaya Kosha*).

2. Kharna (Mind Consecration & Vow Sealing)

Observing a day-long fast, eating a sweet rice-milk kheer cooked over a clay stove at dusk after offering it to the Sun, and commencing the strict 36-hour waterless fast (*Nirjala*).

3. Sandhya Arghya (Honor to the Declining World)

Standing in cold river waters at dusk, offering prayers to the setting Sun (*Pratyusha*), accepting life's cycles, and cultivating mental equanimity.

4. Usha Arghya & Paran (Resurrection of Light)

Welcoming the rising Sun (*Usha*) at dawn with milk/water offerings, breaking the fast with ginger and prasad, realizing the immortal light (*Atma-Jyoti*) within.
