If you are married and have kids, inevitably you will be trapped in the Karmic wheel.
Your in-law family problems become your wife's problems, and your wife's problems, your problems. You think you have solved the problem of procreating for your ancestors, but you also create a new set of problems that you will most likely not be able to resolve within this lifetime. And your children will also create problems, and most of the problems can be attributed to their upbringings which you and your wife are the cause.
The only way to avoid spinning along the cyclic path of the Karmic wheel is to move to the center of the Karmic wheel. This is where everything and everybody around you moves, but you remain stationary. This is where the monks and nuns are supposed to be and in the process escape the Karmic wheel. You watch the world passes by you.
Congratulations to your uncle. He has the chance to end the Karmic cycle of his ancestors and graduates to the next higher dimension of living beings.
