The people in olden days ...
Believes that husband is the light of the house and women is only meant for cooking the food , and have to feed her children and husband. the women is permitted to the kitchen that's it . In olden
days, women ( girls ) are not even allowed to step out of the house .
there is no equality those days , women is discriminated by the men . In
INDIA at older periods, child marriages are done by the people , when
the girl's age is 6 approx and the boy's age is some 60 , like that . so
husband dies fast . when the husband dies then they treated the wife (
widow ) as a statue, they ( uncle / aunt ) will torcher these widows
like any thing . by this,
some people thought that we can save women for these evils . they
supposed were to kill the women . And they started to kill the wife when
her husband dies , she have to die along with him.it is called as " sathi ".
