naham halahalam manye
visam yasya pratikriya
brahma-svam hi visam proktam
nasya pratividhir bhuvi
I do not consider halahala to be real poison, because it has an antidote. But a brahmana’s property, when stolen, can truly be called poison, for it has no antidote in this world.
One who takes a brahmana’s property, thinking to enjoy it, has actually taken the most deadly poison.
