Yo, Krishna, you already know you're the ultimate OG, the source and boss of everything, the God of gods, and the world's ruler, right?
Commentary
Bro, Purushottama is like, the ultimate GOAT among all the Purushas. He's got four major roles: source of everything, Lord of everything, God of all gods, and ruler of the whole world. That's why he's called Purushottama. Devadeva? Dude, even Indra and the other gods worship *him*. Jagatpati? He's the one keeping the world safe and showing everyone the way, using the Vedas as his guide. That's why he's the world ruler.
