He or she has the opportunity to worship the One True God and His Son Jesus Christ and be married again. Any restrictions by any other false religion, Hindi, Islam, etc. do not count as they are false.
Hello Ms Asha, let me ask you a simple question : what do you mean by illegal sex? When two persons are mutually wants to have a physical relations than how could you treat it as illegal. Illegal means forcefully.
Whereas if you are asking about the second marriage than let of clear you All Hindus men and women are free to get into second marriage relation after the death of their first spouse.
Ram's father Dhasarat had many wives. Why he should bother about the death of his wife ? But the case of females, they do not allow to marry more than once. See the pitiable condition of the country's ex-Prime minister Mrs. Ghandi and her daughter-laws.
