Premanand Maharaj Ji
How can I show gratitude to my parents in their old age?
Return your parents' love in their old age
You received your parents' love, and gratitude means loving them the same way now that they are old. A servant will not do this for them.
The love we received from our parents was a favour done to us; out of gratitude, let us love them in the same way now that old age is coming upon them.
