The Vibhuti Yoga chapter 10 in the Gita is truly special.
It starts off with the Lord giving examples of his manifestation in Creation. He gives 54 such examples, like Om, Sri Rama, Prahalada, Kamadhenu and others.
But the best example is towards the end of the chapter, where the Lord talks about Himself as being the Ultimate Vibhuti. How so? Because there is nothing else besides him!
Those who fight over the supremacy of their God over other’s Gods, would be reminded by Krishna that there is only God and nothing but God.
