Manava Dharmashastra 3.31

3.31

jñātibhyaḥ kanyāyā eva pitrādibhyaḥ kanyāyai ca strīdhanaṃ dattvā kanyāyā āpradānam ānayanamāsuro vivāhaḥ | svācchaṃdyāt svecchātḥ, na śāstrata ityāṣārdbhedamāha | tatra hi śāstraṃ niyāmakamasti 'ekaṃ gomithunamiti' | iha tu kanyāyā rūpasaubhāgyādiguṇāpekṣaṃ chandaḥ |

The compound ‘Kanyāpradāna’ is to be expounded as ‘Kanyāyāḥ āpradānam’—the meaning being ‘the carrying away of the maiden.’ This constitutes the ‘Āsura’ form of marriage.

Of his own will;—i.e., in any manner he may chose; not according to rules laid down in the scriptures. This is what distinguishes this from the ‘Ārṣa’ form. In the latter, the scripture restricts the gift to ‘a cow and a bull’ only; while in the present case, the ‘wish’ of the giver shall depend upon the beauty, the character and such other qualities of the bride.—(31).

‘As well as to the bride;’—i.e., by way of ‘dowry.’
