Krishna says in the very next life when you are born again this karma will come to your help and you will start your spiritual journey again from wherever you left up. This is not like other past karma one might say that well that's no big deal all past karma is retained and it's all there so if I do some spiritual reading and meditation and prayer what's there to wonder that that will be there also? Krishna: Whatever they have practiced whatever they have attained is stored up for them and that will come in the verynext life and take over and propel you further.
