Wiki mentions Carlos Gracie was a follower of Helena Blavatsky (Madame Blavatsky) a well known mystic (demonic).

7 rays is an occult practice and demonic and historically became popular in modern times through Blavatsky. Does a lot of mixing with other religions and can stand for many things, even 7 celestial beings. Remember that there is only 1 God, the Father of Jesus Christ.

Some may remember Flynn basically using a word for word "prayer" of Blavatsky which might be why you are wondering why the name sounds familiar. Was a big ordeal back then. https://www.youtube.com/watch?v=MWg9PG6ZE8Y

7 rays and prayer and such come from Blavatsky's book 'The Secret Doctrine" https://www.theosociety.org/pasadena/sd/sd-hp.htm

Anyway, I'd bet there's more pedophiles related to that BJJ academy.
