Krishna connects 9.23 to its root. He is the one who receives all yajnas, the lord of all worship. Whether the devotee knows it or not, every offering reaches him. But those who do not know him in truth — 'tattvena' — they miss the mark and keep wandering.
Knowing someone's name is one thing. Understanding their nature at depth is another. A child knows their mother's name. But as they grow, they begin to see her struggles, her love, her sacrifices — and the relationship deepens. 'Tattvena' asks for that deeper knowing, beyond names and forms.
