Those who take birth in the intermediate order become Shudras. The Shudra rises to the status of the Vaishya; and the Vaishya to that of the Kshatriya. The charge of the duties of his caste succeeds in acquiring the status of a Brahmana. The Brahmana, by following a righteous conduct, acquires Heaven which is full of happiness.
