I am interested to find out where the practice of praising God emanated from? As far as I know there is no where in the Bhagavad Gita that Lord Krishna explicitly says He should be praised. What is the source of sayings like "Jai Sri Krishna/Ram/etc"?
I think at a broader level this applies to all Gods of all religions. If the individual God is all powerful then why the need to praise? The praising isn't going to make the God's more or less powerful.
Edit : The linked question (duplicate) is significantly different to what am asking. I am not interested in finding out where a God says He has to be worshiped. I am specifically after finding out where in Hindu scriptures does any God mention that He has to be praised. Come to think of it, most worship in the scriptures is simply praising God.
