Brāhmanahatya
(重定向自Brahminicide)
Brāhmahatya (also known as Brahma Hatya) is Sanskrit for "the act of killing a Brahmin". Puranic Hinduism considers this act to be a major sin, worse than "ordinary" murder.
In a story involving Indra and Vritra, Brāhmahatya is personified as a hideous goddess.It is a serious crime which has to be faced by the guilty one and his generations in the form of a curse.It is not limited to the killing of a brahmin. It also means killing of all those creatures which are equivalent to brahmin (man-vachan-karma se jo bhi brahmin ho).
