This article, authored by Dr Vamshi Krishna Ghanapathi, presents a comprehensive examination of Grahana Shanti — the corpus of Vedic and Dharmashastra rituals prescribed in response to solar and lunar eclipses. The study situates the eclipse within both its mythological and astronomical contexts, demonstrating that the Indian tradition does not treat these phenomena as mutually exclusive but as complementary layers of a unified cosmological understanding. The Puranic narrative of Svarbhanu, whose severed head and body became the shadow planets Rahu and Ketu following the Samudra Manthan, is analyzed as a symbolic framework that encodes the periodic 'seizing' of the luminaries. Simultaneously, the article acknowledges the precision of classical Indian mathematical astronomy, citing the Surya Siddhanta's accurate identification of the geometric mechanics underlying both lunar and solar eclipses. A central concern of the article is the concept of Sutaka — the state of ritual impurity that the Dharma Shastras assign to the entire universe during an eclipse. The biological rationale for prescribed fasting, beginning nine to twelve hours before the event, is explored through the lens of Jatharagni, the digestive fire held to be weakened by the absence of natural light-rays. The protective function of Kusha (Darbha) grass, placed in food and water containers as a pranic shield against subtle atmospheric changes, is examined with reference to the Smriti Muktavali. The article provides a detailed reading of the Grahana-Shanti-Vidhi as preserved in the Baudhayana Gruhya-Parishishta-Sutra, alongside prescriptions found in the Rigvidhana (3.15.1–4) and the Gautama Dharma Sutra (Adhyaya 16), establishing the textual authority and procedural logic of Homa and Japa during the eclipse period. The paradox of the eclipse as simultaneously impure for physical activity yet supremely efficacious for spiritual practice is foregrounded, with the Shastras asserting a 100,000-fold amplification of merit for mantra recitation performed during this interval. The article concludes with an analysis of the Moksha phase — the moment of eclipse release — encompassing mandatory Snana, the ritual bath, and Dana, the act of charitable giving, both understood as mechanisms for restoring cosmic balance.
