I can only say, I don´t have a good feeling with this whole Metatron thingy... something is fishy. Also, is it just a coincidence, that this name is so similar to the bad guy in the Transformers movies Megatron? I know these guys love those wordplays, like right in your face...
I also don´t like most modern esoteric teachings, this has brought to us many wannabe-gurus.
I know the music-bizz and hollywood is riddled full of satanic occult fuckers.

One has to wade through a lot of crap in this to see the true essence in it. The symbolism is essential for understanding. So much fucked up shit going on there.
I also don´t think much of those proclaimed healing ceremonies, or let´s rather say am a sceptic.
I prefer to just be from the heart, though I´ve knowledge, I wouldn´t use it for any ceremony. Real magic comes from the heart. That´s what I believe.
