Om Shanti,
Everybody can get rid of attachment by strong meditation. But i think 100% achievement is possible only at the last moment. But if you can win against the 5 vices, then you can enjoy total freedom, i.e. MUKTHI in your life even before leaving the present body. And you can go straight away to the Golden Age as well.
Like any study, this Godly study also do have numberwise students. So transfer of a soul to the Golden Age depends on the quality of ones study.
