Buddhism does not regard marriage as a sacrament - it is purely a secular affair, and normally Buddhist monks do not participate in it (though in some sects priests and monks do marry). Hence marriage receives no religious sanction. Forms of marriage, in consequence, vary from country to country. The Parabhava Sutta states that "a man who is not satisfied with one woman and seeks out other women is on the path to decline". Other fragments in the Buddhist scripture seem to treat polygamy unfavorably, leading some authors to conclude that Buddhism generally does not approve of it or alternatively regards it as a tolerated, but subordinate, marital model.
