There is some karma that you might realize in this birth but as I said in the post
Karma transcends many cycles of life, it is not an instant cause and effect, but may come about from a previous lifetime.
It may come about from a previous lifetime and also your karma may not come to fruition until the next life.
That is true - the ultimate goal is to
eradicate all karma so that you don't have to return at all
Break that cycle of rebirth!
