While preaching we face lots of questions like all upanishads glorify their God as supreme.
we refer them as upanishads being of goodness, passion and Ignorence. But can't refer where it is actually written .
They say vedas are original without any partiality.
where in Vedas do we find krishna is supreme and others are his subordinates ? Please give some quotes
it will help to convince both myself and others.
Please do not give quote of Bhagwat gita , srimad bhagwatam or any satvik upanishads.
You can give links to posts if it has already been discussed.
