Mbh 1.73.4

“Dushmanta replied, ‘O beautiful and faultless one, I desire that thou shouldst be my life’s companion. Know thou that I exist for thee, and my heart is in thee. One is certainly one’s own friend, and one certainly may depend upon one’s own self. Therefore, according to the ordinance, thou canst certainly bestow thyself. There are, in all, eight kinds of marriages. These are Brahma, Daiva, Arsha, Prajapatya, Asura, Gandharva, Rakshasa, and Paisacha, the eighth. Manu, the son of the self-create, hath spoken of the appropriateness of all these forms according to their order. Know, O faultless one, that the first four of these are fit for Brahmanas, and the first six for Kshatriyas. As regards kings, even the Rakshasa form is permissible. The Asura form is permitted to Vaisyas and Sudras. Of the first five the three are proper, the other two being improper. The Paisacha and the Asura forms should never be practised. These are the institutes of religion, and one should act according to them. The Gandharva and the Rakshasa form are consistent with the practices of Kshatriyas. Thou needst not entertain the least fear. There is not the least doubt that either according to any one of these last-mentioned forms, or according to a union of both of them, our wedding may take place. O thou of the fairest complexion, full of desire I am, thou also in a similar mood mayst become my wife according to the Gandharva form.’
