in lord Buddhas time their was many kingdoms in India. these kingdoms had many kings. kings had many wives. some kings had 500, 1000 (Antappura) wives but they all have main 1 queen & other wives used for sex uses.most of these kings became followers of Buddhism & Buddha & they obtain nirvana (1st 3 stages as below)
The First Stage – Skt srotaapanna (The stream-winner)
The Second Stage – Sakridagamin
The Third Stage – Anagamin (The non-returner)
so my question is after these became Buddhist & obtain nirvana did these kings given freedom to these Wives who use for sex uses?
