That Shudra who is truthful in speech and who has controlled his senses, is considered as having acquired meritorious penances. Indeed, the Shudra, who having got a guest, performs the duties of hospitality towards him, is considered as acquiring the merit of great penances.
स शूद्रः संशिततपाः सत्यवादी जितेन्द्रियः। शुश्रूषुरतिथिं प्राप्तं तपः संचिनुते महत्॥
