Is hiding past relationships a sin? Like if women lie before marriage because if she reveals it, she won't get married. Or if a man hides his past relationships and marries a clean women, for getting married. Can one avoid these out in any way, like through rituals or any from or sacrifices. Their was an article saying when a man/women marry in front of sacred fire and rituals, they will share thier sins.
Yes, it is a sin.
For both men and women.
- Though (a man) may have accepted a damsel in due form, he may abandon (her if she be) blemished, diseased, or deflowered, and (if she have been) given with fraud.
If a woman is not virgin, and she hides it before marriage, the marriage can be 'annuled'. There is only 1 marriage for women (barring rare exceptions).
For men, it is slightly different. They have to be brahmachari (virgin/celibate) until their 1st marriage. And this rule doesn't just mean not having sex with a woman. It includes all forms of sexual thoughts/practices (porn/masturbation etc.)
Those who know the Veda declare that a voluntary effusion of semen by a twice-born (youth) who fulfils the vow (of studentship constitutes) a breach of that vow.
The divine light which the Veda imparts to the student, enters, if he breaks his vow, the Maruts, Puruhuta (Indra), the teacher (of the gods, Brihaspati) and Pavaka (Fire).
When this sin has been committed, he shall go begging to seven houses, dressed in the hide of the (sacrificed) ass, proclaiming his deed.
Subsisting on a single (daily meal that consists) of the alms obtained there and bathing at (the time of) the three savanas (morning, noon, and evening), he becomes pure after (the lapse of) one year.
