Premanand Maharaj Ji
My elderly parents won't give up their old habits. Should I still serve them?
Serve elderly parents without conditions
Your duty is to bring comfort to aged parents, and do not set conditions for serving them. Remember how your mother and father cared for you.
Do not impose conditions on them, that they must give this up or we will serve. If they give it up, good. If not, you must not abandon them.
