[fullmetal alchemist brotherhood] what was truth trying to say to father before dragging him back inside the gate of knowledge?

Never understood truth whole monologue to father, I know father gate is completely blank implying that he didn’t learn anything but is that all truth was trying to communicate?

The truth was essentially telling Father that he was wrong, that he wasn't, and never was better than humans. That stealing power from others did not make him strong, and that he was every bit as conceited as the humans he derided earlier when he said Truth existed to punish boastful humans. He was telling him that for all the power he had amassed, he still understood nothing, and that for that he deserved to be, and would be punished.

Juxtaposed with this is his talk to Edward in his final transmutation, where he calls Ed's choice to give up alchemy the right answer. Ed states he doesn't need, alchemy, as long as he has the connections to the people he has come to rely on. The Truth's point, as can be seen across these two interactions, is that what is valuable, what makes someone strong and worthwhile, is not the power they amass for themselves, but rather the connections and relationships they build with others, that trusting and relying on each other is what really matters.

And so, Truth punishes the one who didn't learn to be bound forever, while giving the one who did grow and learn exactly what he wanted for so long.
