The Law Code of Devala 3.2: Kṛtyakalpataru · Gṛhastharatnākara

3.2

tato vinītāṃ kalyāṇīṃ kanyāṃ kulavayo'nvitām | alaṃkṛtyārhate dadyād vivāho brāhma ucyate

How should their bathing, how their cleansing, how their penance be? / What conduct should they adopt? Tell us that in full detail.”

When one adorns a well-bred, virtuous maiden of good family and right age and gives her to a worthy man, that marriage is called Brāhma.
