Premanand Maharaj Ji
What if my parents behave badly with me or my wife — do I still have to serve them?
Serve helpless parents even if they scold
When parents can no longer manage on their own, serve them even if they abuse you. Their minds weaken after 60–70, so do not take their words to heart.
The day they reach a state where they cannot look after themselves, you should serve them even if they abuse you.
