6.3.239.7

brahmahatyāsamaṃ pāpaṃ bhavitā neha kiṃcana .
kathaṃ vā dhautapāpe tu praviṣṭaṃ naśyate dvija .
etadvistarataḥ sarvaṃ pṛcchāmi vada kautukāt .. 184.7 ..

There is no sin here equal to the killing of a brahmin. / How then does that which has entered Dhautapāpa perish, O twice-born one? / I ask all of this in detail; speak out of curiosity.
