RIP and Godspeed Master Helio. There are many hacks who run around calling themselves masters and I hesitate to use the term for anyone.
Master Helio is an exception.
He pushed our understanding of combat into an entirely new place while never forgetting to do it with dignity and honor. He left the world something that has saved many lives(maybe even my own once or twice) while inspiring legions to improve as human beings.
A truly amazing man and a historic figure.
I hope he is somewhere teaching Bruce Lee the guard right now.
