For that matter no rule on this earth was created by God.
Every institution has its own set of rules. A school has its own, an office has its own, a club has its own, a church has its own and a temple has its own. Rules are always framed with good intentions, but over the years, people interpret it in their own ways, to suit their vested interests. That is how evil practices like Sati came into existence in Hindu society. No where it is said that a woman has no right to live, once her husband passes away. Of course manu has said ' na stree swatantram arhathe' - no women deserve freedom. This was quoted in the context that a female while in her younger days is under the guardianship of hr parents, in youth once married off, undedr her husband and the old days under their son/s. Not only Hindu religion, but every sect in the4 world perhaps considered women as something 'precious' You must have heard of Kunchan Nambiar's poem in which he said all clashed in this world are attributed to two factors - kanakam and kamini, i.e. wealth and women. In hinuduism, women enjoyed a lot of privileges, especially in Kerala where Nair community was dominent.
