If, indeed, the Shudra wishes to be a Vaishya (in his next life), he should also abstain from meat of animals not killed in sacrifices. If a Vaishya wishes to be a Brahmana (in his next life), he should perform these duties. He should be truthful in speech, and shorn of pride or arrogance. He should be above all pairs of opposites. He should observe the duties of peace and tranquility.
वृथामांसं न भुञ्जीत शूद्रो वैश्यत्वमृच्छति। ऋतवागनहंवादी निर्द्वन्द्वः शमकोविदः॥
