People have become so degraded in this age that on the one hand they restrict polygamy and on the other hand they hunt for women in so many ways.
Many business concerns publicly advertise that topless girls are available in this club or in that shop. Thus women have become instruments of sense enjoyment in modern society. The Vedas enjoin, however, that if a man has the propensity to enjoy more than one wife – as is sometimes the propensity for men in the higher social order, such as the brahmanas, kshatriyas and vaisyas, and even sometimes the sudras – he is allowed to marry more than one wife. Marriage means taking complete charge of a woman and living peacefully without debauchery. At the present moment, however, debauchery is unrestricted. Nonetheless, society makes a law that one should not marry more than one wife. This is typical of a demoniac society.
