If a brāhmaṇa cannot support himself through his regular duties and is thus suffering, he may adopt the occupation of a merchant and overcome his destitute condition by buying and selling material things. If he continues to suffer extreme poverty even as a merchant, then he may adopt the occupation of a kṣatriya, taking sword in hand. But he cannot in any circumstances become like a dog, accepting an ordinary master.
