Here? No, Not really. It's difficult enough to teach intent in person. Suffice to say it is an old and established way to train the mind/body to connect and move and in so doing your movement, and the effect it has on others, is more profound.
And contrary to Chris Hein's dig, it's pretty much universally embraced by everyone who is truly doing internals.
