I hadn't heard of Braco until this question and have only briefly scanned through his website but the fact that all he does is offer a silent gaze to heal does remind me of something.

Abraham once briefly explained how Jesus was able to pull off apparently miraculous healings.

Their explanation was that he was able to ignore current reality and see a sick person in his presence as well despite any physical evidence to the contrary. So while someone "sick" was in that vibrational field of "wellness", they were so heavily influenced towards wellness that it caused them to heal themselves. In other words, the belief of wellness dominated their own vibrational field causing a shift in their own belief system.

I think it's a little like what happens with clattering but instead of clattering out of your reality, someone comes along for the ride with the improved vibration.

Abraham also explained that this was why Jesus then told those people not to tell others about what had happened...so that their new beliefs would not go back to how they were (and recreate those previous "negative" physical manifestations) because of the influence of disbelievers/skeptics.

I don't know enough yet about Braco to know if he is actually doing something like this. But, if he is, then he might just be anchoring a vibrational field of "wellness" within himself that forces others who focus upon him (using his gaze as a focal point) to be influenced towards that "wellness" themselves.

Just my best guess for now :)
