A saying goes thus "he who lives by the sword dies by it" and another says "you reap what you sow". These of course are still convergent on the karma effect.
Now here is an example, my mum do tell me when I was much younger that " obey your parents so that your kids will obey you too when you grow older".
The question is, if for instance my kids do not listen to me because I disobeyed my parents when I was young, does that mean my kids (when they grow up) will be disobeyed by their kids too? Considering the fact that they are just innocently completing the karma effect on me
