In Vedic society no girl was allowed to remain independent and unmarried. Independence for women means they become like prostitutes, struggling to capture some man who will take care of her. In this way the so called independent woman has to work very hard to make herself attractive by artificially wearing cosmetics — mini skirts and so many other things. Formerly the girl would be married to a suitable boy at a very early age, say six years old. But although a girl was married early she did not stay with her husband immediately, but was gradually trained in so many ways how to cook, clean and serve her husband in so many ways — up until the time of her puberty. So all the time there was no anxiety because a girl would know — I have got a husband, and the boy would know I have got this girl as my wife. Therefore when the boy and girl would come of age there was no chance of illicit sex-life. And the pychology is the first boy that a girl accepts in marriage, that girl will completely give her heart to, and this attachment on the girls side for her husband becomes more and more strong, thus if a girls gets a good husband — one who has accepted a bona fide spiritual master and is firmly fixed up in his service, automatically the wife of such a good husband inherits all the benefits of his spiritual advancement. So you are fortunate. Go on in this present attitude, serve you husband always and in this way your life will be perfect, and together husband and wife go back home — Back to Godhead.
