Brahmahatya (), also rendered Brahmanahatya () is the Sanskrit term for "the killing of a Brahmin". It is translated as Brahminicide in English. The Manusmriti regards the murder of a Brahmin to be the greatest of sins, and the highest of the mahapatakas (mortal sins).
Brahmahatya is also personified as a hideous woman in Hindu texts such as the Puranas. Described to possess red hair and wear blue robes, she is stated to laugh boisterously, chasing the murderers of Brahmins.
Literature
The Ramayana describes the conflict between Indra and Vritra. After Indra slays Vritra, he incurs the sin of brahmahatya and is immediately paralysed, falling unconscious. The deities arrange for the purification of Indra's sin with the performance of the ashvamedha sacrifice. In the same epic, to expiate Rama's sin of brahmahatya for the killing of Ravana, Sita creates a lingam out of sand for the worship of Shiva, which was installed at the temple of Rameswaram.
The Matsya Purana describes the legend of Shiva's form of Bhikshatana. Having decapitated one of Brahma's heads, Shiva incurs the sin of brahmahatya, with the skull of the deity stuck to his palm. For the atonement of this sin, the deity assumed the guise of a mendicant and wandered across the land until he reached Kashi, where he achieved redemption.
Some texts state that bathing at the water bodies of a tirtha, a Hindu site of pilgrimage, cleanses one of the sin of brahmahatya.
