A Hindu born woman marrying a non-Hindu man gets stuck post life as there is no gati planned by Universe for such souls. They can be born again only after full destruction which takes place some time every 12000 yrs. At the same time, a non Hindu born marrying a Hindu, enters Moksha cycle, which is not possible for a non-Hindu. Non-Hindus can enter Moksha cycle by taking a Hindu brahmin as their Guru, and changing their prayer methods to that of a Hindu. In such case, no Varna or jati needs to be assigned unless the person’s ancestors Varna jati is known. By extension, all non-Hindus i.e. Mlechchhas are Chandrawanshi Kshatriyas.
