Hindu marriage definitely allows remarriage of some kind. I am no expert it just a lucky shot. Wife of Parasara, satyavati married santanu. All her subsequent children were the children of santanu. Since Vyasa was never adopted by santanu he remained the son of his father parasara.Agreed if you are applying logic of Hindu Dharma here.But just a question...I know Hindu Dharma has no Divorce..then would a subsequent 2nd marriage of the divorced girl be invalid in the eyes of Hindu Dharma?
Thats why I once had said in this thread when the DNA of anyone cant change why the hassle of a Gotra change?
Body is supposed to be a garment which is discarded upon death why are we renaming it?
Dont get me wrong please I am no Atheist or reformist ....just asking a few points thats all.
On the other hand Kunti's brief relations with the devas did not change her marital status.
So I do not know about kanyadhan system in this story.
But otherewise the logic of marriage in mahabharata seems as follows
Husband and wife together marriage valid. Children belong to father's lineage.
Husband and wife separate (Parasara and Satyavati), wife is free, goes back to father and marriage as per the rites. Satyavati's father still in control of second marriage. Conclusion if women returns back to father the marriage is in her father's control. The children remain in their own father's gotra. Adoption of anyone is permissible so that changes situations. I would assume that vedic writers would assume that adoption of a dead man's only varisu would be considered cheating and is not necessary for the new husband of his wife.
Husband and wife together. Wife is not separated . Any other relations of wife, children belong to married husband and not to the donor.
Donor worthy then wife is secure. Donor unworthy wife is thrown out.
This is in brief law as seen in Mahabharat.
Husband died, wife can get a child through husband's blood links. It means any brother of husband or husband's father or husband's father's brother and so on. Child belongs to Husband's vamsa only.
