Parashara said In the Brahmana, wealth gained by acceptance of gifts, in the Kshatriya that acquired by victory in battle, in the Vaishya that acquired by performing the duties laid down for his order, and in the Shudra that acquired by serving the three other orders, however small it may be, is worthy of praise, and when spent for the acquisition of virtue yields great benefits. The Shudra is said to be the constant servitor of the three other orders.
