And to take care of your parents when they are alive is also filial. But to help their soul and to liberate them after they pass away, that’s even more filial. Like in many Buddhist stories that we have heard, that even can rescue the mother from hell. Even from the nonstop hell. Like Maudgalyayana or like Ksitigarbha Bodhisattva when He was still a human being.
So, is it nice that you are a practitioner? You can always see your parents even when they pass away and even can continue helping them to elevate spiritually. So that’s the most filial deed you can do for your parents.
