17. For the Sudras who were constituted of the qualities of Rajas and Tamas, and whose mind was full of insolence on account of the Rajas (passion) and was intoxicated with riches and drink, who always put to suffering the race of brave brahmins full of divine presence, who always proceeded by the crooked path and who found amusement in doing violence to other lives, their action in sacrificing the Brahmin was most horrible and cruel—the Brahmin who was the sage and Brahman himself, the son of a Brahmin sage and who was quite harmless, nay, the friend to all creatures, the killing of whom could not be permitted even in any great crisis. Noticing this act of theirs the goddess made her appearance (issuing from her image in the temple), with her body burning as it were owing to the unbearable force of the Brahmin’s virtue.
