What episode did Leo say this: “That beauty is maddening”?

Evening all

Leo said this to describe the beauty of consciousness, does anyone recall what episode it was from? I believe the  context went something like this: “and people will wonder, what’s up with that person? There seems to be something different about him/her. Whats different about you is you’ve witnessed the beauty of consciousness. That beauty is maddening”.

 

Thnx

Dunno which specific episode, but that’s exactly what he feels when he opens his mouth or sheds a tear
