3.10.p6

"There are eight forms of marriage—namely, Brāhma, Daiva, the Arsha, Prajāpatyā, Asura, Gāndharba, Rākshasa and Paisācha and the last is the worst. And every one should marry according to the mode enjoined to his caste by the sages and should never marry according to the Paisācha mode. Thus entering the order of householders, if a man takes a wife observing the same religious and civil obligations and perform all the ceremonies of his orders in her company, he derives great benefit from such a wife".
