If a Vaishya, after having taken birth as a Kshatriya, performs the usual purificatory rites, becomes invested with the sacred thread, and betakes himself of the observance of vows, he becomes, in his next life, an honoured Brahmana.
स वैश्यः क्षत्रियो जातो जन्मप्रभृति संस्कृतः। उपनीतो व्रतपरो द्विजो भवति सत्कृतः॥
