Premanand Maharaj Ji
How should a grown son serve his parents in old age?
Worship parents at home
Worship the parents in your home like Bhagwan: serve them, stay in their command and bow daily. A son who serves parents this way attains Bhagwan on his own.
Worship the parents seated in your own home like Bhagwan. Serve them, live by their word, and bow to them daily.
