No, devotees are not allowed more than one wife. Devotees should have no wife if possible, but those who cannot maintain celibacy, they can marry one wife. At the present moment people are so unfortunate they cannot maintain even one wife. First of all at the present moment they are not married and remain mostly unmarried. So for such persons even one wife is a great burden. Under the circumstances how one can think of more than one wife? This is stupidity.
